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. Legacy and Current AT&T Servers: New accounts cannot use the following servers: Legacy 1 Servers smtp1.attglobal.net - Auth SMTP Server, for Dial-up/Business Users smtp2.attglobal.net - Same as smtp1.attglobal.net mailhost.att.net - Unknown No/Auth?

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.
