thanks z3r010,
ok Im assuming your using one of the following two e-mail programs, if not then just let me know.
For Windows Mail:
1) Open Windows Mail
2) Click 'Tools' at the top of the window
3) Select 'Accounts' from the drop down menu
4) On the list, there should be a catogory called 'Mail', select 'your e-mail account' and cllick 'properties' on the right
5) Click 'Servers' at the top of the window
6) in the 'Outgoing Mail Server (SMTP)' make sure it says 'mail.bellsouth.net'
7) at the bottom of that window make sure the small box is has a tick in it called 'My Server Requires Authentication'8) click 'OK' then 'Close'
For Microsoft Office:
1) Open Microsoft Office
2) Click 'Tools' at the top of the window
3) Select 'Account Settings' from the drop down menu
4) Select Your Account in the list
5) Click 'Change'
6) in the 'Outgoing Mail Server (SMTP)' make sure it says 'mail.bellsouth.net'
7) click 'More Settings' and then click 'Outgoing Server' from the top
8) make sure that the box titled 'My outgoing server (SMTP) requires authentication'
7) make sure the first option 'Use same settings as my incoming server' is selected
8) click 'ok', click 'next', click 'finish', click 'close'
now test your mail again
[edit]
Iv also just tryed to telnet (a program for connecting to servers) your mail server, it is not letting me connect on the smtp port, however it is letting me connect to the pop3 server (incoming mail). If the above dose not work contact them asking if there is any problems at there end.
