Testcases for folder expiry:
Automatic expiry:
- normal case (ensure folder has old mails and expiry settings, wait for auto-expiry)
- having the folder selected when the expiry job would run (gets delayed)
- selecting a folder while an expiry job is running for it (should interrupt)
- exiting kmail while an expiry job is running (should abort & delete things cleanly)
Manual expiry:
- RMB / expire (for one folder) [KMMainWidget::slotExpireFolder()]
- RMB on Local Folders / Expire All Folders [KMFolderMgr::expireAll()]
- Expire All Folders [KMMainWidget::slotExpireAll()]
