SMTP Server Mail List (AT&T)     2012/02/12-13
by Ami Sapphire

Updated 2012/02/14
[0214] - Found and confirmed missing POP boxes for six Legacy 1 servers, thus
completing the list for that server group. However, there is a list of legacy
local mailhost.*loc*.ameritech.net servers for Legacy 2 that I don't even feel
like entering in this list, thus making it incomplete.

This is a list of legacy and Yahoo! SMTP mail servers. This list came about
when I was setting up my local email addresses for my website, and I am using
the smtpauth.sbcglobal.net one (of course). ;D

The Yahoo! Servers are listed after the legacy list.

Current Legacy Servers are for older SBC entity and current AT&T Yahoo! users.

Legacy 1, 2, and Current Legacy use port 25 for SMTP and port 110 for POP3.

All Yahoo! SMTP Servers use either port 25 or 587 with Authentication (SSL with
port 587) with either your ISP email or your own email, provided you added it
to the verified list of your ISP email. There are apparently no sending mail
limits. Attachment size limits are 20MB, and 30 recipients max in one email.
This is all from memory.

All Yahoo! POP servers use either port 110 or 995. Same method as the SMTP
servers.
