 /*
  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()]
