annoyed rant #3: Leopard Mail.app

I've just moved back to Mozilla Thunderbird as my mail client on all of my Leopard machines. I thought I had the IMAP, IDLE, mail delete/trash problem licked, but no luck. Deleted messages keep coming back from the dead, and I'm tired of having a full inbox as a result. Bye-bye mail.app; nice try, but you're far from a robust mail client. Long live Thunderbird.
