+1. Double check the error handling and review error message in various
+ failure modes.
+2. Implement the CHUNKING extension (rfc 3030; as soon as I find an
+ SMTP server that supports it).
+3. Better error message (translated standard meanings of the known
+ response codes, ENHANCEDSTATUSCODES extension (rfc2034)).
+4. (KIO) MultiPutJob to support pipelining across messages.
+5. Ged rid of slave's header generation after checking who on earth
+ uses that...
+
+and further refactoring to make the code pleasant to look at ;-)

+ * @short Represents an SMTP command
+ *
+ * Semantics: A command consists of a series of "command lines"
+ * (though that's stretching it a bit for @ref TransferJob and @ref
+ * AuthCommand) and responses. There's typically one response for
+ * one command line and the command is completed.
+ *
+ * However, some commands consist of a dialog (command line,
+ * response, command line, response,...) where each successive
+ * command line is dependant on the previously received response
+ * (and thus those commands are not pipelinable). That's why each
+ * command signals completion by having it's @ref #isComplete()
+ * method return true @em after the last command line to be sent,
+ * but @em before the last response to receive. @ref AuthCommand is
+ * the principal representative of this kind of command. Because
+ * @ref EHLOCommand automatically falls back to HELO in case EHLO
+ * isn't supported, it is also of this kind. If completion is
+ * signalled before the first command line is issued, it is not to
+ * be executed at all.
+ *
+ * Other commands need to send multiple "command lines" before
+ * receiving a single (final) response. @ref TransferCommand is the
+ * only representative of this kind of "command". That's why each
+ * command signals whether it now expects a response before being
+ * able to issue the next command line (if any) by having it's @ref
+ * #needsResponse() method return true.
+ *
+ * Commands whose @ref #nextCommandLine() does not support being
+ * called multiple times in a row without changing command state,
+ * must reimplement @ref #ungetCommandLine().

+ (Format: TXT=192504 bytes) (Obsoletes RFC0821, RFC0974, RFC1869)

+Known shortcomings:
+- Doesn't enforce the CRLF lineending convention on user-supplied data.
+- Due to the lack of a Mulit_Put_ in the KIO infrastructure, pipelining
+ across messages isn't supported.

+ @short A class modelling an SMTP transaction's state
+
+ This class models SMTP transaction state, ie. the collective
+ result of the MAIL FROM:, RCPT TO: and DATA commands. This is
+ needed since e.g. a single failed RCPT TO: command does not
+ neccessarily fail the whole transaction (servers are free to
+ accept delivery for some recipients, but not for others).
+
+ The class can operate in two modes, which differ in the way
+ failed recipients are handled. If @p rcptToDenyIsFailure is true
+ (the default), then any failing RCPT TO: will cause the
+ transaction to fail. Since at the point of RCPT TO: failure
+ detection, the DATA command may have already been sent
+ (pipelining), the only way to cancel the transaction is to take
+ down the connection hard (ie. without proper quit).
+
+ Since that is not very nice behaviour, a second mode that is more
+ to the spirit of SMTP is provided that can cope with partially
+ failed RCPT TO: commands.
