My fix is typically to delete the offending message from my Sent Items 
list in MailMate, and then quit/restart and synchronise the mailbox, or, 
I will export the messages (this morning it was five or six messages) 
into an "mbox" format, then delete them from MailMate, quit MailMate, 
then use Mail.app to re-import them to IMAP (works fine), and re-start 
MailMate.

Not ideal, but, it prevents me losing mail.

(If it matters, Benny, I tend to use command-return as a shortcut to 
send messages)
