in many ways. You can reach it via
SettingsConfigure
&kmail;....It is divided into six
pages, each of them represented by one of the
icons in the list on the left hand side of the dialog. Below the pages
will be described in detail.The dialog has several buttons:HelpThis will open this manual at the appropriate page.DefaultsThis will reset the configuration options on the current
page back to the default values.Load Profile...This will open a dialog which offers several configuration
profiles. You can use these as starting points for your own configuration.ResetThis resets all changes you have made since you last saved
the settings.OKThis saves the settings and closes the configuration dialog.ApplyThis saves the settings without closing the configuration
dialog.CancelThis closes the configuration dialog without saving the
changes you have made.Identities PageYou can find a quick introduction to the
Identities page in the Getting Started section.This page allows you to create one or more
Identities, &ie; combinations of name, email
address and other settings. For example, you can create one identity
for business communication and one for
personal communication. If you have more than one email
address, you can create one identity per address. You will then be
able to select an identity on a per-message basis.The page consists of a list of identities and buttons to manage
them. The identities list will always show at
least one identity, which is then the Default
identity.To add a new identity to the identity list, click on the
New... button.
The New identity dialog
will then appear.The New Identity DialogYou have to enter the name of the new identity into the
New Identity edit field. This will be the name
shown in the identity list.You can choose how the new identity should be initialized by
checking one of the three radio buttons in the middle of the
dialog:With empty fieldsAll fields of the new identity are cleared or preset with
standard values.Use Control Center settingsUses the settings of the Control
Center's default email profile (you can edit that one
under Internet & NetworkEmail in the
Control Center).Duplicate existing identityCopies all fields from an existing identity. You can
choose which identity to copy from by selecting the corresponding
entry in the Existing identities popup.GeneralThe General tab allows you to specify some
basic settings for the currently selected identity.Your nameEnter your full name here (sometimes also called display name).
Although this field is not strictly mandatory, it is recommended to enter
the correct value here.OrganizationEnter your organization here. This field is optional.Email addressEnter your email address here, &ie; something like
joe@example.com.ExampleSo if your address is Joe User
<joe@example.com>, you should enter Joe
User into the Your name field and
joe@example.com into the Email
address field.
Cryptography
The Cryptography tab allows you to
specify &openpgp; and &smime; keys associated with this
identity, as well as choosing the preferred (cryptographic)
message format to use.
OpenPGP signing key
Here you can select the key to be used when
&openpgp;-signing messages written with this identity in
effect.
For brevity, only the short key id of selected keys is
shown. Hovering with the mouse over the key list will
show more information in a tooltip.
To clear the label press the
Clear button.
To change the selected key, press the
Change... button. A dialog
listing all secret &openpgp; keys will be shown allowing
you to select the one to use.
OpenPGP encryption key
Here you can select the key to &openpgp;-encrypt
messages to when this identity and
are in effect. This key is also used for the
function of the Composer.
To change the selected key, press the
Change... button. A dialog
listing all &openpgp; keys found in your keyring will be
shown allowing you to select the one to use.
You can clear the list of keys and get more information
about them in the same way as described for .
&smime; signing certificate
Here you can select the certificate to be used when
&smime;-signing messages written with this identity in
effect.
To change the selected certificate, press the
Change... button. A dialog
listing all secret &smime; signing certificates will be
shown allowing you to select the one to use.
You can clear the list of certificates and get more
information about them in the same way as described for
.
&smime; encryption certificate
Here you can select the certificate to &smime;-encrypt
messages to when this identity and
are in effect.
To change the selected certificate, press the
Change... button. A dialog
listing all &smime; encryption certificates found in
your local keybox will be shown allowing you to select
the one to use.
You can clear the list of certificates and get more
information about them in the same way as described for
.
Preferred crypto message format
Here you can choose which cryptographic message format
to use by default with this identity.
You can either select any of the four formats supported
by &kmail; or leave the option at the recommended
default setting of Any, which will
choose a suitable format based on the recipients of the
message, or might even go so far as to create two copies
of the message, one &smime; signed and/or encrypted, the
other &openpgp; signed and/or encrypted.
AdvancedThe Advanced tab allows you to specify some
rarely used or otherwise specialized settings for the currently
selected identity.Reply-To addressEnter the address to which replies to your messages should be
sent. Only fill out this field if it is different from your normal
address (specified using the Name and
Email Address on the General
tab), since replies default to the sender's address
anyway.This field is only useful if you want replies to your mail
to go somewhere else than your regular email address, ⪚ if you are
using this identity to send messages from an email address that cannot
receive messages. Note that
some mailing lists overwrite this header field with their post address to
make sure that replies go to the list instead of individuals. So the
usefulness of this field is very limited and it should only be used in
rare cases.BCC addressOptionally enter an address to which blind copies of your messages
should be sent to. Note that a BCC is only send to this address, when
ViewBCC
is activated while composing a message. If you want to send a BCC regardless
of this setting, you should look at the Headers tab of the
Composer page.Sent-mail folderSelect the folder into which messages should be filed after sending
when using this identity. IMAP users should consider changing this to an
IMAP folder, so their sent-mail is stored on a server instead of being
stored in a local folder. This way they can access these messages at a
different location.You can exercise more fine-grained control over where to
file sent messages by creating a corresponding message filter that is applied to outgoing
messages.Drafts folderSelect the folder into which drafts should be filed when using
this identity. IMAP users should consider changing this to an
IMAP folder, so their drafts are stored on a server instead of being
stored in a local folder. This way they can easily continue to work
on their drafts at a different location.Special transportSelect or enter an alternative SMTP server to be used when sending
messages using this identity.You need to configure outgoing mail servers first, before
you can choose them from the list. You can do this on the Sending
tab of the
Accounts page.SignatureThis tab allows you to specify a signature (sometimes called
footer or disclaimer)
to be appended to each message sent using this identity.This type of signature has nothing to do with the
(digital) signatures for which you can select the keys to use on
the Cryptography
tab. It is just bad wording to call this a signature, but since
the term is already used everywhere else, we keep this notation. Just
keep in mind that these signatures and digital signatures are two
completely different things.Check the Enable signature option if you
want to be able to append the signature when using this identity. To
automatically append it to every new message
you also have to select Automatically append
signature in the Composer configuration page.&kmail; can obtain the signature text from various sources. The
traditional way on Unix is to read the text from a file called
.signature in your home folder. This file can
be shared between several programs, so you get the same
signature in each mail program you use.To read the text from a text file you select
Obtain signature text from file. Enter the
filename in the Specify file edit field or hit
the button to the right of it to browse your filesystem. If you want
to edit the file, hit the Edit File
button.&kmail; can also read the signature text from the output of a
command. Thus, you can use programs such as
fortune to create a new signature text for
every message. Everything the program prints onto
stdout is caught and used as the signature
text.To read the text from the output of a command you select
Obtain signature text from Output of
Command. Enter the command (preferably with full path) in
the Specify command edit field.As a third option, you can enter the signature text directly in
&kmail;'s configuration dialog. To do this, select Obtain
signature text from input field below and enter the text
into the appearing text box.On the Internet, signatures are by convention separated
from the body of the message by a line containing only the three
character -- (dash, dash, space). &kmail; will
automatically prepend the signature text with this line if it is not
already present in the signature text.If you do not wish the separator to be prepended
automatically by &kmail;, simply add it to the signature
text yourself.Accounts PageYou can find a quick introduction to the
Accounts page in the Setting up your Account
section.This page allows you to create one or more (incoming and
outgoing) accounts, &ie; combinations of mail
servers, login information and other settings. Typically, you will
create one outgoing (used for sending messages) and one incoming (used to
retrieve messages) account. You can create as many accounts as you want, though,
and assign each one to different identities or decide on a per-message
basis.SendingThe Sending tab allows you to define new
outgoing mail servers and set some common options.For basic information, see Setting up your Account: Sending.When you click Add... or
Modify... the Add
transport or Modify transport dialogs
will open respectively. For sending via sendmail
or similar programs
you can specify a name and the location of the
sendmail program. For SMTP you
can specify Name, Host, and
Port of the server. Server requires
authentication will enable the Login
and Password fields and the
Authentication method buttons on the
Security tab. If you are not sure about the
security settings you can make &kmail; test for the best settings by
using Check What the Server Supports.Confirm before send will pop up a
confirmation box every time you send a message.Send messages in outbox folder lets you specify
when queued messages, &ie; messages in the outbox folder pending to be sent,
should be sent. You can choose between:Never AutomaticallyQueued messages will only be sent if you select
FileSend queued messages.On Manual Mail ChecksQueued messages will be sent after you have manually checked
for new mail, ⪚ with FileCheck Mail. Of course, you can also
manually send the queued messages with
FileSend queued messages.On All Mail ChecksQueued messages will be sent after all checks for new mail,
&ie; after automatic mail checks as well as after manual mail checks.
Of course, you can also manually send the queued messages with
FileSend queued messages.Default send method lets you define what
happens when a message is sent. If Send now is
selected, the message is sent to the mail server immediately, while if
Send later is selected, the message is queued in
the outbox to be sent later with the
FileSend
Queued Messages command or automatically when you
check your mail, depending on the setting of
Send messages in outbox folder above.Message property lets you select how your
message will be encoded when it is sent. Allow
8-bit means that &kmail; will send your message in 8-bit
ASCII, which means that all special characters such
as accented letters will be sent as-is. If MIME Compliant
(Quoted Printable) is selected, special characters will be
encoded using standard &MIME; encodings, which may be more portable to
mailing systems other than 8-bit ASCII.
We recommend to use MIME Compliant.Even with Allow 8-bit
selected &kmail; will use MIME
Compliant encoding in some situations, for
example for sending cryptographically signed messages.Default domain lets you specify which domain name
should be used to complete email addresses that only consist of the recipient's user
name. For example when you set the default domain to kde.org
then messages you send to johndoe will be sent to
johndoe@kde.org.ReceivingFor basic information, see Setting up your Account: Receiving.Check mail on startup lets you specify whether
KMail should check for new mail immediately after it has been started.With New Mail Notification you can set
how &kmail; will notify you if new messages have arrived:
Beep will play a short beep sound;
if Detailed new mail notification is enabled then
&kmail; will show the number of new messages for each folder provided
you have chosen to be notified with a dialog. More advanced
notification options, like showing a dialog or running a certain command,
are available via the Other Actions button.Appearance PageFontsThis section allows you to change the type, size and character set of the
display fonts. Message Body sets the font for
the reader pane, Composer sets the font for
writing messages in the composer window.
There is a separate entry for Message List - Date Field
so you can choose a monospaced font for the date field for better readability.ColorsThis section allows you to change the color of the text.
Recycle colors on deep quoting means that even text that is
quoted more than three times will appear in color. Note that the
Quoted text colors only work in the message reader, not in
the composer. If you want folders which are close to their quota
(space alotment, usually used on IMAP servers) to be displayed in a different color,
you can specify a percentage value as a threshold for this. The color to be used
can be configured along with the other custom colors.LayoutShow HTML status bar activates a bar at the left side of the reader
pane that tells you if a message is &html; or not. This is important because
&html; messages might imitate the look of a signed and encrypted message, so
you should be aware of the fact that you are reading a &html; message. The &html;
status bar itself cannot be influenced by the &html; code of the message.The Window Layout section lets you choose the
layout of the main window. You can choose where you want the
Message Preview Pane or choose not to have
it at all.The Message Structure Viewer option lets you choose when
the structure viewer will be shown: the structure viewer is a part of the main window that
lets you access all parts of a message. Show never will
disable the structure viewer (note that you can still access attachments as icons),
Show always will show the structure viewer even if there is only
one plaintext part. Show only for non-plaintext messages will
display the structure viewer only if it makes sense, &ie; if the current message
has attachments or has &html; parts.HeadersWith Display message sizes selected there will be another
column in the header pane that shows the messages' size.Show crypto icons will add more status information
to the Subject columns in the header pane: every message
that has been signed will have a small Signed icon in front
of the subject, every message that has been encrypted will have a small
Encrypted icon in front of the subject. Note that you have
to select a message once before these icons will appear, until then only
question marks will be displayed.Thread list of message headers will put all the messages
in the header pane in a kind of tree list, so that the replies to a message are
directly below that message.With Message header threading options you can select
whether threads should appear expanded (open) by
default or whether they should be collapsed (closed).
You can of course still open/close threads using the +/-
buttons.With Date Display you can choose between several
date formats. The Localized Format is the one you can
specify under Country & Language in &kcontrol;.
For the Custom format you can get
a description of the possible values by pressing
&Shift;F1
and then clicking on Custom option.System TrayIf you enable the system tray icon then a small &kmail; icon with the
number of unread messages will be shown in the system tray. You can enable
&kmail;'s system tray icon with Enable system tray icon,
and with System Tray Mode
you can specify whether the tray icon should always be shown or only if
you have unread messages.If the icon is visible then you can hide &kmail;'s main window by
clicking on the icon or by clicking on the window close button. By clicking
on the icon you can make &kmail;'s main window visible again.
If you click on the icon with the right
mousebutton then you get a menu with a few useful commands. You can check
for new mail, create a new message or quit &kmail;. Additionally, there is
the entry New Messages In which lists all folders
containing unread messages. If you choose one of those folders then this
folder will be selected in &kmail;'s main window.
Composer Page
General
Automatically append signature
If checked, your signature as defined in the identity
page is automatically included at the end of
all messages you create (&ie; new messages, replies, &etc;).
Use smart quoting
If checked, &kmail; will break long lines but will try
to keep the correct quoting (⪚ the >
will always be at the start of the line).
Automatically request message disposition notifications
If checked, will default to
on. Check this option only if you
know what you are doing. &mdn;s are considered a
nuisance (or are simply ignored) by a lot of people. It
is better to decide to request them on a
message-by-message basis.
Word wrap at column
Lets you turn word wrapping on and off in the composer
window and lets you set the column at which words will
be wrapped (you probably should not need to change the
default value, which is 78).
Autosave interval
A backup copy of the text in the composer window can be created
regularly. This option lets you specify the interval used to
create the backup. You can disable autosaving by setting it to
the value 0.
External Editor
If you do not like the Composer you can use a different
editor. Note that the composer window will still open
and the external editor will open as soon as you type
just one character in the body of the message. If you are
done, save the text and exit the editor. The text will
now appear in the composer window, where you can send
it. Note that your editor may not return immediately,
you have to use ⪚
gvim %f for gvim.
PhrasesThe Phrases tab lets you define the automatically
generated lines that are added to message replies, forwarded messages, and the
character that is added in front of quoted text.
There are special %-denoted characters that will insert certain
values, which are also displayed at the top of the Phrases section.
You can add reply phrases in languages other than
your default &kde; language using the Add... button.
You can then choose between different languages with the
Language drop down box.
This will only work for languages whose i18n package you have installed.SubjectThis section contains a list of prefixes for Reply and
Forward. If you receive messages that use prefixes different
to the standard ones, you can add them here so &kmail; will recognize
them. This way &kmail; can ignore them for sorting messages and
when setting the subject of a reply or a forwarded messages, and optionally
replace them with Re: or Fwd:
respectively.CharsetHere you can manage the default charsets used for your own messages.
Every message you send will be checked if it is written in one of the listed
charsets, starting at the top of the list. If it is, this charset will be used.
If it is not, a dialog will show up and tell you that you manually have to choose
a charset using
OptionsSet Encoding.
If you select Keep original charset when replying
or forwarding (if possible), the original message's charset
will be kept, unless there are now characters that cannot be
represented using that charset.HeadersCheck the Use custom message-id suffix
checkbox if you want &kmail; to generate Message-Id's with a custom
suffix. Enter the desired suffix in the Custom message-id
suffix field. Please make sure that the suffix that you
specify is world-wide unique. The best thing is to use the name of a
domain which you are the owner of. If you do not check Use
custom Message-Id suffix then &kmail; will automatically
generate the complete Message-Id. If you do not know what this is all
about do not check this option.The Define custom mime header fields list
sets the headers that &kmail; will use for its outgoing messages. You
can both invent new fields and overwrite existing ones. This feature
is only useful for advanced users.AttachmentsIf you have to send attachments with filenames containing non-English
characters to users of Outlook(TM) or Outlook Express(TM) then you might want
to check the Outlook-compatible attachment naming option.
&kmail; will then encode the attachment names in a non-standard way that is
understood by Outlook(TM).Note that &kmail; will create non-standard compliant messages, and
consequently it is possible that your messages will not be understood by
standard-compliant mail clients. So, unless you have no other choice, you
should not enable this option.Check the Enable detection of missing attachments
checkbox if you want &kmail; to warn you whenever you are about to send a
message without attachments although the message text contains certain
words which indicate that you wanted to include an attachment. The list
of key words can be modified.
Security Page
Reading
On this tab you can configure security-relevant options for
reading messages.
Prefer HTML to plain text
If checked, &kmail; will show &html; messages with their
&html; formatting and layout. We strongly recommend to
leave this option off, as security problems with &html;
might show up. When this option is off, you can still
read &html; messages, but only as plain text.
Allow messages to load external references from the Internet
If checked, &kmail; can load external images, style
sheets &etc; from the Internet when you look at an
&html; message. We strongly recommend to leave this
option off (although it has no effect if you only view
plain text messages). By adding external references to
their messages, people sending spam can detect that and
when you have looked at their message. Note that this
option has no effect on &Java;, JavaScript and Plugins -
these are disabled anyway and cannot be enabled at all.
Message Disposition Notifications
&mdn;s are a generalization of what is commonly called a
read receipt. The message author requests
a disposition notification to be sent and the receiver's
mail program generates a reply from which the author can
learn what happened to his message. Common disposition
types include displayed (&ie; read),
deleted and dispatched
(⪚ forwarded).
The following options (listed as Send
policy) are available to control
when &kmail; sends &mdn;s:
Ignore (recommended)
Ignores any request for disposition
notifications. No &mdn; will ever be sent
automatically.
Ask
Answers requests only after asking the user for
permission. This way, you can send &mdn;s for
selected messages while denying or ignoring them
for others.
Deny
Always sends a denied
notification. This is only
slightly better than always
sending &mdn;s. The author will still know that
the messages has been acted upon, he just cannot
tell whether it was deleted or read &etc;
Always send
Always sends the requested disposition
notification. That means that the author of the
message gets to know when the message was acted
upon and, in addition, what happened to it
(displayed, deleted, &etc;). This option is
strongly discouraged, but since it makes sense
where privacy is not a concern, ⪚ in customer
relationship management, it has been made
available.
If you are unsure, experiment a while with
Ask and if you find &kmail;s
questions annoying, switch to Ignore.
The following options (listed as Quote
original message) are available to control
how much of the original message
&kmail; sends back in &mdn;s.
Nothing
No parts of the message other than the mandatory
message-id and the original recipient is included
in the &mdn; reply. This preserves enough
information for the sender to find the message in
his sent messages for which this &mdn; was
generated.
Full message
Attaches the complete message to the disposition
notification. Usually, this is overkill. It does
not add any valueable information that cannot be
deduced from the message headers alone, but people
sometimes insist on this, since it is much easier
for humans to correlate the content of the message
than just the headers to what they sent earlier.
Only headers
Attaches only the headers to the disposition
notification. This is usually enough to enable
both humans (by subject) and computers (by
message-id) to easily correlate &mdn; and original
message.
If unsure, leave the option at the default.
Do not send MDNs in response to encrypted messages
This option suppresses the sending of &mdn;s if the
message is encrypted (partially or in whole). This
thwarts attempts to use &kmail;'s &mdn; feature as an
oracle to deduce whether you were
able to decrypt the message or not.
Strictly speaking, this option is not needed, since
&kmail; sends &mdn;s regardless of whether the message
could be successfully decrypted or not (the disposition
notification request resides in the unencrypted part of
the message), but it gives the security-conscious user
the choice to either send them always if requested
(option unchecked), or never (option checked).
If unsure, leave the option checked.
Automatically import keys and certificates
If checked, &kmail; automatically imports any attachments
containing &openpgp; keys into your local keyring, and any
attachments containing &smime; keys into your local key
box.
Verifying &smime; signatures always involves importing
the contained certificates. This option thus does not
affect this. It is also unrelated to &gpg;'s
feature, where &gpg;
will try to import unknown keys from a key server.
Composing
On this tab you can configure security-relevant options for
composing messages.
Automatically sign messages
If checked, the option in the
composer will default to on.
However, you can still switch it on and off on a
per-message basis.
Always encrypt to self
If checked, any message that is encrypted to the
recipients will additionally be encrypted to yourself.
If you uncheck this option, you may not be able to
decrypt the messages written by yourself and encrypted
to other people anymore.
Store sent messages encrypted
This options enables a mode of using mail encryption
that is sometimes (misleadingly) called
transport-only encryption. In this mode
of operation, the message encryption is stripped off
as soon as the message has reached its
destination. The encryption lasts only while the
message is on its way.
&kmail; supports this mode half-heartedly, since such
functionality should better placed at the mail
server (MTA)
than at the mail client
(MUA) level. Thus, future versions
of &kmail; may drop support for this option.
If checked, messages are stored in your
sent-mail folder just as you sent
them (&ie; if they were encrypted, they are also stored
that way).
If unchecked, messages will always
be stored unencrypted in your
sent-mail folder, even if they are
sent encrypted.
Always show the encryption keys for approval
If checked, everytime you encrypt a message, a dialog
will appear that presents you with the encryption keys
that will be used for each recipient. You can then
review the choice of keys, change them, and approve or
cancel the encryption operation. We recommend to keep
this option checked, since it makes the encryption
process more transparent.
Automatically encrypt messages whenever possible
Also called opportunistic encryption. If
checked, &kmail; will try to match recipients to
(&openpgp; or &smime;) keys even when you did
not specifically request
encryption. If usable keys are found for all recipients,
&kmail; will ask whether or not you want to encrypt the
message.
It is highly recommended to turn this on, as it makes
encrypting messages really easy to use.
Never sign/encrypt when saving as draft
If checked, &kmail; will not attempt to sign and/or
encrypt messages that are merely saved to the
drafts folder. This is more
convenient, and does not result in a gross loss of
security, provided the drafts folder is safe. &imap;
users might want this options turned off, if their
drafts folder is on the server.
Warnings
On this tab you can switch security-relavant warnings on and
off.
Warn when trying to send unsigned messages
If checked, &kmail; will show a warning if for whatever
reason a message would be sent without being digitally
signed.
Warn when trying to send unencrypted messages
If checked, &kmail; will show a warning if for whatever
reason a message would be sent without being encrypted.
While it is common to sign all outgoing messages,
encrypting them is not. So unless your company has a
policy of never sending any unencrypted messages, it
might be a good idea to keep this option switched off
and rely on opportunistic
encryption to alert you if you
could send encrypted messages,
but did not request it.
Warn if receiver's email address is not in certificate
If checked, &kmail; will emit a warning if an &smime;
certifciate or &openpgp; key will be used for a recipient
whose email address is not listed in the email addresses
stored in the certificate.
Situations in which this warning will trigger include
when configuring your per-identity &openpgp; keys or
&smime; certificates, when encrypting, and when verifying
signatures, if the signature was made with a certificate
that does not include the email address of the sender.
Warn if certificates/keys expire soon
If checked, &kmail; will warn when an &smime; certificate
or &openpgp; key is used which will expire soon.
The period in which to warn before key/certificate
expiration can then be configured separately for signing
and encryption keys, as well as (in the case of &smime;),
for end-user certificates, intermediate
CA certificates and root
certificates.
Re-Enable All "Don't Ask Again" Warnings
Apart from the main warnings described above, there are
more warning and information messages, which contain an
option to not show them again. If you would like to
re-enable them after choosing not to show them again,
you can achieve this by pressing this button.
This will re-enable all such
warnings for &kmail;. It does not make much sense to
allow more fine-grained selection of which warnings
to show since you can just check the option to
suppress them again when they next show up.
&smime; Validation
This tab contains selected entries from &gpgsm;'s dynamic
backend configuration dialog. Please refer
to the &gpgsm; manual for a description of these options.
Validate certificates using CRLs
If checked, &smime; certificates are validated using
Certificate Revocation Lists (CRLs).
Validate certificates online (OCSP)
If this option is selected, &smime; certificates are validated
using the Online Certificates Status Protocol
(OCSP).
Fill in the URL of the OCSP
responder in the field reserved at this effect.
OCSP responder URL
Enter the address of the server for online validation
of certificates. The URL
is usually starting with http://.
OCSP responder signature
Select or change and enter the &smime; key to use.
Ignore service URL of certificates
Check this option to skip online validation using the OCSP.
This Option requires dirmngr >= 0.9.0.
Do not check certificate policies
By default, GnuPG uses the file
~/.gnupg/policies.txt to check if a
certificate policy is allowed. If this option is selected,
policies are not checked.
Never consult a CRLs
If this option is checked, Certificate Revocation Lists are
never used to validate &smime; certificates.
Fetch missing issuer certificates
Check this option if you want the missing issuer certificates
to be fetched when necessary. This applies to both validation
methods, CRLs and OCSP.
Do not perform any HTTP requests
Entirely disables the use of HTTP for
&smime;.
Ignore HTTP CRL Distribution Point of certificates
When looking for the location of a CRL,
the "to-be-tested"certificate usually contains
what are known as CRL Distribution Point (DP) entries,
which are URLs describing the way to access
the URL. The first found DP
entry is used.
With this option all entries using the HTTP
scheme are ignored when looking for a suitable
DP.
Use system HTTP proxy
If this option is selected, the value of the
HTTP proxy shown on the right
(which comes from the environment variable http_proxy)
will be used for any HTTP request.
Use this proxy for HTTP requests
Enter here the location of your HTTP Proxy,
which will be used for all HTTP requests
relating to &smime;.
The syntax is "host:port", for instance
myproxy.nowhere.com:3128.
Do not perform any LDAP requests
Entirely disables the use of LDAP for
&smime;.
Ignore LDAP CRL Distribution Point of certificates
When looking for the location of a CRL,
the "to-be-tested" certificate usually contains
what are known as CRL Distribution Point (DP) entries,
which are URLs describing the way to access
the URL.
The first found DP entry is used.
With this option all entries using the LDAP
scheme are ignored when looking for a suitable
DP.
Primary host for LDAP requests
Entering a LDAP server here will make all
LDAP requests go to that server first.
More precisely, this setting overrides any specified host
and port part in a LDAP URL and will also
be used if host and port have been omitted from the
URL. Other LDAP servers
will be used only if the connection to the
proxy failed.
The syntax is HOST or
HOST:PORT. If PORT is
omitted, port 389
(standard LDAP port) is used.
Crypto Backends
On this tab you can configure which crypto backends are to be
used for &openpgp; and &smime; cryptographic operations (such
as signing and encrypting).
On the right-hand side, you see a list of available
backends. Below each backend entry, you can see what protocols
(&openpgp; and/or &smime;) the backend supports. If a protocol
is not listed, the backend does not support it. If it is
listed, but greyed out, the backend supports the protocol, but
some required programs were not found, or other errors
occurred during initialization. If you press
Rescan, a dialog box will appear that
lists reasons for the initialization failure.
To configure a backend, select it in the list of available
backends and press Configure.... The
per-backend configuration dialog is dynamically created from
the information returned by the backend. It may therefore
change if you update the backend applications, although
&kmail; itself is unchanged. If the
Configure... button is disabled, the
backend does not support a backend configuration dialog.
Please refer to the manuals of the applications underlying
each backend for a description of the options presented in the
backend configuration dialogs.
In front of each backend's protocol entries, you can see a
checkbox, with which you select which backend is to be used
for a given protocol. These checkboxes are exclusive per
protocol, meaning that if you select a backend to perform
&openpgp; operations, any previously selected &openpgp;
implementation will be unselected, but the &smime; backend
selection will be unchanged. If no backend is selected for a
given protocol, that protocol is effectively disabled for use
in &kmail;.
Misc PageFoldersAsk for confirmation before moving all messages to trashEnable this option if you want to be asked for confirmation whenever
you use FolderMove All Messages to Trash.Exclude important messages from expiryEnable this option if important messages should never be deleted
during message expiration, &ie; during automatic deletion of old
messages.When trying to find unread messagesThis option controls what happens if you press one of the shortcuts to
go to the next or previous unread message (⪚ Space).
If you ask &kmail; to go to the next unread message although there is no
unread message below the currently selected message then the following happens:
If Do not Loop is selected then nothing will happen.
If Loop in Current Folder is selected then &kmail;
will search from the beginning of the current folder for an unread message. If
none is found then nothing happens.If Loop in All Folders is selected then &kmail;
will first search in the current folder for another unread message. If none
is found then &kmail; will search the next folder containing unread messages.
Correspondingly, if you ask &kmail; to go to the previous unread message.
Jump to first unread message when entering a folderIf this option is enabled &kmail; will go to the first unread message
when you enter a folder; if it is not enabled, &kmail; will go to first
new message or, if there is no new message, to the message
that was selected when you last left the folder.Mark selected message as read after...When you select a new or
unread message, &kmail; will change the
message's status to read after the number of seconds
entered here. If you disable this option, messages will keep their
new or unread status.Ask for action after dragging messages to another folderWhen you drag a message to a different folder, a small popup will ask
you if you want to move or copy the message. If you disable this option,
the message will be moved immediately, without a popup.By default, message folders on disk are...Here you can set the default folder format
that is used when you create a new folder.Open this folder on startupHere you can set the folder that should be selected by default if you
start &kmail;. If you use only &imap; folders then you might want to set
this to your &imap; inbox folder. If you do that, you can collapse the local
folders in the folder list, and then they will stay collapsed when &kmail;
starts.Empty trash on program exitThe trash folder is cleared of messages when you quit &kmail; if this
option is selected.GroupwareEnable IMAP resource functionalityMakes it possible to store the entries from the Kontact applications (KOrganizer, KAddressBook and KNotes). This option has to be set whenever you are configuring Kontact as a KDE Kolab client. This option being enabled you will also need to add the appropriate resources from the KDE Control Center (kcontrol) in the KDE Resources Configuration section. Kolab resources have to be added in case the resource functionality applies to a KDE Kolab client set-up.Format used for the groupware foldersChoose the storage format for the groupware foldersDefault format is Standard (Ical/Vcard) for calendar folders (Ical) and addressbook folders (Vcard). This makes all Kontact features available.Kolab users should choose Kolab XML. This format uses a custom model that matches more closely to the one used in Microsoft Outlook(tm) and gives better compatibility.Language of the groupware foldersChoose between the available languages to set the folder names of the IMAP storage to your local language. Note that this option is only aimed for compatibility with Microsoft Outlook(tm). It is not recommended to change its default unless you have to, since it makes changing languages impossible.Resource folders are in accountSelect the parent of the IMAP resource folders. You should select the name of your IMAP/DIMAP account. By default the Kolab server sets the IMAP inbox to be the parent.Hide groupware foldersYou should not need to see the folders that hold the IMAP resources. However if you want to see them, you can set that by enabling this option.Mangle From:/To: headers in replies to invitationsEnable this option to make Microsoft Outlook(tm) understand your answers to invitations replies.Send invitations in the mail bodyInvitations use to be send as attachments to a mail. By enabling this option, you let the invitation mails to be sent in the text of the mail, which is necessary to send invitations and replies to Microsoft Outlook(tm).Options without a user interface representation
Apart from the options presented in the configuration dialog, some options
can only be set directly in the configuration file ($KDEHOME/share/config/kmailrc)
or through KIOSK.
Send Message Distribution Notifications with an empty sender string (SendMDNsWithEmptySender)
Send Message Disposition Notifications with an empty sender string. Some servers might be configured to reject
such messages, so if you are experiencing problems sending MDNs, make sure this option is set to false. To
enable this feature, add a line reading:
SendMDNsWithEmptySender=true
to the [MDN] section of the kmail configuration file. If there is no such section, simply add "[MDN]" on
a line by itself just above the option.
Note that the default setting of "false" strictly speaking violates internet standards, but is
set that way for practical reasons, to avoid servers rejecting MDNs that KMail generates because they
think they are SPAM.
Allow Semicolon As EMail Address Separator (AllowSemicolonAsAddressSeparator)
In RFC2822, the comma (,) is the only allowed separator for email addresses in fields like To, CC and BCC. This option allows to also use the semi-colon (;) as separator. This only affects the user interface, the created messages still use commas only and thus do no violate the standard.
The option is enabled by default. To disable the feature, add a line reading (under [Composer] section):
AllowSemicolonAsAddressSeparator=false
ForwardingInlineByDefault
This option allows you to make inline forwarding the default forwarding method instead
of forwarding as attachement.
To enable the feature, add a line reading (under [Composer] section):
ForwardingInlineByDefault=true
MaximumAttachmentSize
This allows the maximum file size allowed for attachments in the mail
composer to be limited.
To limit attachments to 20 MB ins size, for example, add a line reading (under [Composer] section):
MaximumAttachmentSize=20
CloseDespiteSystemTray
This option allows you to configure the application to close fully, even if there
is a system tray icon configured, which would normally keep the application running.
To enable the feature, add a line reading (under [General] section):
CloseDespiteSystemTray=true
CheckOutOfOfficeOnStartup
With this option enabled, KMail will check on every startup if there is an
active out-of-office configured and show a warning if this is the case.
To disable the feature, add a line reading (under [OutOfOffice] section):
CheckOutOfOfficeOnStartup=false
disregardUmask
This option allows you to disregard the users umask setting and use "read-write for the user only".
To enable the feature, add a line reading (under [General] section):
disregardUmask=false
AutoLostFoundMoveActivate this option to automate the handling of not yet uploaded messages in disconnected IMAP
folders that can not be uploaded. This can happen if the folder was removed from the server or your access
rights have been restricted. Such messages will automatically moved to a newly created lost+found folder if
this option is enabled, you will be ask how to proceed everytime otherwise.
To enable the feature, add a line reading:
AutoLostFoundMove=trueto the [Behaviour] section of the configuration file
