/*
 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()]
