I missed a bit of that discussion, but does the above tell postfix to actually relay through that server or does it tell postfix to "spoof" that server on HELO?


If the latter, it won't work. I've also configured my mail server at work to block incoming mail from adsl, cable, and dial-up IPs and host names. This is because all of the mail that we receive from those domains is spam. When a machine connects to send us mail, our mail server does a reverse DNS look up on their IP. It ignores what is sent in the HELO, unless the other machine is sending our own IP or host name in the HELO, in which case the connection is rejected.

AOL is doing more or less the same thing with their servers.

I have absolutely no problem with doing this because it cuts down on the spam we receive and if you are trying to run your own mail server over such an account, you are generally in technical violation of your AUP.
