Replying once again to my own message as today I am holiday and therefore playing with my MailMate settings!

I have
    MmAutomaticExpungeBehavior = never;
    MmDeleteBehavior = markAsDeleted;

So I can see deleted messages in my current mailbox. But as I have reported before, if I switch to a different mailbox, then the marked as deleted messages are expunged, as if I had MmAutomaticExpungeBehavior = mailboxSwitch;

Most perplexing. Ideally I want to control when expunging takes place OR perhaps I might settle for expunging when I cleanly exit/shut down MailMate. I suppose I could try MmDeleteBehavior = moveToDeletedMessages; and see what impact that has on my workflow. Do any of you have this hidden preference set and can provide comment?

(Primarily Tuffmail - and they are not doing an automatic expunge)
