Thought I would share what I found from another source. This worked for me (using comcast):
in settings, select mail, email, contacts. Select "add account." Select "other."
Address =
yourmail@comcast.net
Enter yr password
Select the new email account
Under "incoming mail server" you shd have: mail.comcast.net
Under "outgoing mail server" you shd have: smtp.comcast.net
select: smtp.comcast.net
Under "primary server" you shd have: smtp.comcast.net
Select it. On mine I had to set "Usee SSL" to ON. it says the primary server port is :587
Go back one level. Under "SMTP" I had to turn off all the servers listed under "other SMTP servers"
Go back one level: under 'outgoing mail server" select "Advanced"
Under "incoming settings,' turn on "Use SSL' ON
Thanx to VB at the wireless forum from AT&T!
oh ... and the constantly checking for mail problem? Nut behind the wheel: had the "Push" feature on ...
