Ever since I've updated to the latest Mac Mail program, I'm having nothing but problems with sending mail.  In the outgoing server list, when you disable SSL it simply re-selects itself.  You can't turn it off.  This creates significant problems as there are no SSL certificates installed for the mail server.

Has anyone else experienced this?  Any solutions?  I've tried pretty much everything and still the same.  Others I know are starting to have similar problems.  There have been Mac OS X updates since and no fix for this problem as yet.  It's not cool.
