This is weird. My wife and I both have iPhones and use the same Comcast service for our internet/mail. The only difference between our phones is that mine is set up on a PC and hers on her iMac. However, I can send and receive my mail on my iPhone, but the wife's won't allow her to send.
Comcast requires password authentication for outgoing mail but, rooting through the Advanced menu in the Mail/Settings, I found that my wife's iPhone has Outgoing Mail Authentication set to "On", but the option as to which type of authentication is greyed out.
Mine is set to "Password" and I have the password entered on the main Mail setup page. Hers won't hold a password entered on the main page as we cannot set the authentication type to "Password".
This is an ongoing problem that does not get fixed by a restore. I doubt it's anything to do with mine being on PC and hers Mac (unless it was the other way around). So, I'm out of ideas...
