I had the same problem and went through various senarios. WHen I am on my home wifi, I had no problems. My outgoing mail server was set to Smtp.comcast.net but once I connect to edge it will NOT let me send any emails. so I have to change the outgoing email server to ATT's cwmx.com. I called comcast and they told me that they don't support iphones and they did not wanna bother.I have a Comcast email address, and I was unable to send emails from my iPhone. I went to the Apple store and they helped me figure it out. Here is what you do if you are having problems... Go to "Settings", then "Mail", then click on your email account...click on outgoing mail host name and erase the ":452"...
you should now be able to send email...
Yeah I talked to Comcast before I went to the Apple Store, and they did not want to help me one bit with the iPhone!! They suck! My outgoing email works for me on Edge and wi-fi. That's weird that it won't work for you!I had the same problem and went through various senarios. WHen I am on my home wifi, I had no problems.
