I get "Expired Server Certificate" notifications every time the account Inbox is checked (every few mins). There should be a user preference to IGNORE THIS Reproducible: Always Steps to Reproduce: 1. Use the Mail client to connect to an IMAP server over SSL which has an expired certificate 2. Get the dialog "Expired Server certificate" every time. Actual Results: Expired Server Certificate dialog can't be "dismissed forever". Expected Results: There should be a button and/or user preference to "ignore this from now on".

I think this is a wontfix, the server certificate should be fixed. You should not use SSL if you don't need the security.
