Re: New at&t/Yahoo install. FINALLY got Outlook email to send. If you use any Yahoo based server, smtp.XXX.yahoo.com, then you have to do the address authentication. It's their way of limiting how much mail can be pumped through the server. Otherwise, I would use them as a smarthost for my company's Exchange server.
You can't just move to a new provider and expect SMTP to work. For one, ATTIS blocks by default any communication on port 25 to any SMTP server other than their own. Lot's of ISPs do this, it's a spam prevention measure.
Second, even if there wasn't a port 25 block going on, you probably wouldn't even be able to use your SMTP server anyways. ISPs, if they don't require SMTP authentication, usually implement an ACL on SMTP servers, to prevent non-customers from using their servers for spam.
So, forget about saying it "works" on the T1. It's irrelevant to using AT&T DSL. It's going to work on the T1 because of the two issues stated before, and it won't work on AT&T DSL because of the two issues stated before.
If you don't want to use Yahoo's email address verification, switch your outgoing mail server on ALL your accounts to smtpauth.sbcglobal.net. It requires authentication, of course, which is your new AT&T email address and password. No SSL, no different ports, just SMTP on port 25 with authentication.
You have to do this to ALL your accounts, no if's and's or but's.
You are making this much more complicated than it needs to be. |
