I am having a difficult time sending e-mail from Mail. I am using my .mac account with the SMTP info coming from my provider not the .mac SMTP.I am with Cox Communications who just became Sudden Link. I had no trouble until the change over and believe it is coming from blocked ports. I understand they block port 25 and have changed ports with no luck. I have also changed my SMTP information to reflect the changes from Cox to Sudden Link. I have spent a fair amount of time chatting live with customer support but when I get to the Mac OS X part I am told they can't help. I even tried rapido SMTP with no success. Anyone have any suggestions? I am really confused and any help would be appreciated.
