deleted messages reappear in Inbox
It's been awhile since this happened, but it's happened again, and after rebuilding the mailbox, deleted messages continue to reappear in my inbox.
I've search in this discussion, and tried steps recommended in similar threads. So far I have: backed up the home>Library>Mail and rebuilt the mailbox. I've tried the Apple article about deleting old 10.3 mail files in the mboxes. And I've tried deleting messages in Mail app, quiting Mail app, and moving all .emix files in Deleted Messages.mbox to the desktop trash. Afte this last process, I can't empty the desktop trash, so I ran Onyx to force emptying trash. Then restarted.
Deleted messages have returned to my Inbox.
What the **** can I do next?!
