I am unable to send Emails since Mail app was updated. I have checked with my ISP (RCN.com) and all my settings are correct. Except the the server address has the Email Address as a part of it. This is not correct and my ISP feels this is what is causing the send mail to fail.
iMac, OS X Mountain Lion (10.8.1)
