Since I'm 99% sure the idea (or stupidity thereof :-) of blocking SMTP servers without reverse DNS came up here in this discussion, I just ran a manual queue run to clean out a queue, and saw this come up: ... Connecting to mailin-04.mx.aol.com. via esmtp...220-rly-xn05.mx.aol.com ESMTP mail_relay_in-xn5.9; Wed, 03 Dec 2003 09:59:55 -0500 220-America Online (AOL) and its affiliated companies do not 220- authorize the use of its proprietary computers and computer 220- networks to accept, transmit, or distribute unsolicited bulk 220- e-mail sent from the internet. Effective immediately: AOL 220- may no longer accept connections from IP addresses which 220 have no reverse-DNS (PTR record) assigned. >>> EHLO westnet.com I don't know if this is new -- I don't recall seeing it before, but it doesn't say they WILL refuse, just they may. If they do start blocking -- this WILL be an operational issue. ========================================================== Chris Candreva -- [email protected] -- (914) 967-7816 WestNet Internet Services of Westchester http://www.westnet.com/
