Each Knowledge Base entry can be edited again and again and, of course, trashed. Nothing, it's freely distributable. Changelog Changes in 0.6 Deleted mails can now be undeleted again and put back into the Inbox. Small code clean-ups. This feature is not very well implemented, but should work and not produce too many bad things like mail loops or responses to mailing-lists.
Minor bug fixes.
This release should fix the errors. Sure, I always need a helping hand.
