Reporter Alexander, Want to let you know that Magnus has a solution that should resolve the comcast issue. There will be a new pref you will be able to set ```false``` called ```mail.smtpserver.default.cache_connections```. This will cause each message to go out on its own TCP/SMTP connection as occurred with 102. The change should be in daily fairly soon but has not yet landed. So probably don't need a comcast account to test this on.
