Re: What is Qwest's SMTP server address?
said by Suffering  :Actually most most mail servers in the US won't relay third party domains. Cite your proof? I don't know how to prove it one way, or the other; but I have tested some U.S. mail providers which do relay third part domains. I even use them:
smtp.pacbell.yahoo.com
smtpauth.sbcglobal.net
smtp.gmail.com

While I can't cite anything specific I do know that open mail relay hasn't been too popular for some time. I remember using open relays to mail bomb friends back around 1994 when email was more novelty than necessity (at least it was to us).

None of the big providers, ISP or otherwise, run open relays. Heck, I run a mail server on my residential connection and I have secured it against relay. There may be even as many as 100 open relays on the entire Internet. Oh, and I will add a hyperbole warning on that number. I have no way to determine a realistic estimate. About once every month, or so, I see attempts at unauthorized relay; I have to presume that the spammers will find one almost as fast at it appears.

Looks like there are actually TONS of open relays (unfortunately) »www.ordb.org/statistics/relaycount/ way more than I thought there would be
