+ 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()]
