[NTLUG:Discuss] AOL Rejecting Mail and Sendmail

[Chris J Albertson]

I had the same problem. AOL decided to block my ip address a few weeks back. So,
I went about trying to figure out why. They do some really nice portscanning of
servers that send them email.
1) They don't like open relays. (Obvious here. Most NTLUGers wouldn't do that
anyway)
2) They don't like open proxies. (That one got me. Squid was running on an open
port. Nice eh?)
3) They don't like people who send them a lot of emails for user accounts they
don't have. I believe they have this set at about 90%. Meaning, if 11% of your
mailings are "recipient unknown," you end up on their blacklist.
4) They subscribe to mail-abuse.org RBL. Check there for your listing.

You can go to this link: http://postmaster.info.aol.com/
They will tell you how to get yourself removed. Start praying you're not on the
mail-abuse.org list. If you are, you're on your own there. I've not gotten on
that one yet. Don't want to be either.

In a nutshell, you can ask aol.com to scan your ports again and let you know
where you fit. If you have fixed everything when they re-scan you, they'll let
you play again. Worked for me.

Good luck to you. You should not be forced to send mail thru your ISP unless
that's the way you want to go, or comcast makes you do it.

I hope this helps.

 Add to the mailertable
 
 .aol.com	smtp:[mail.comcast.com]
 
 I think you missed the brackets in your first try.  The brackets will
 tell sendmail to ignore your MX for SMTP delivery to that (aol.com)
 domain.  Don't forget the leading "." on domain the to relay.  Also do
 not have aol.com listed as a local domain.
