Candelyn,
Try this, step by step. Open OE, go to Tools, Accounts,
under the Mail Tab open properties. Under the General Tab
in the first white area should be "mail.comcast.net"
(don't use the quotaion marks), Name area should have you
name, email address area should have your e-mail address.
Make sure the little box on the lower left is also
checked. Now go under the Servers tab. My Incoming box
should be: POP3, Incoming POP3 box should be:
mail.comcast.net, Outgoing should be: smtp.comcast.net,
the account name should be your e-mail address, enter your
password in the password area, check the little box to
remember your password. Now click apply & OK. That should
be it. You should now exit OE and reboot. You can then
try sending yourself an e-mail to see if it gets through
OK.
Good Luck !
