Sorry, I misread your response above. So they're GONE in the webmail mailbox too. If your provider has Deleted Item Retention running you might be able to recover them from there. If you go to Tools | Account Settings | E-mail Accounts select your IMAP account, click Change then More Settings do you have a Deleted Items tab? Do you have a radio button for "Mark items for deltion but do not move them automatically? Do you have any rules running?
