John T, Thanks for pointing me part way to the answer. If Andrew had not asked the question again and I had not gone out to figure out what he was talking about I would not have found out that I had the same issue. If you had told him the complete solution at first I would not have checked my configuration and would have just assumed mine was set up correctly because I had no backups in my mail queues.

When the other email system tries to look up the ip address via a reverse dns lookup the ip address lookup returns mail.autosoldnow.com. These two names are clearly not the same so the other email server will think you are a spammer. You need your exchange server to claim it is mail.autosoldnow.com when it tries to send mail not asnmail.autosoldnow.local WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 <http://www.dnsstuff.com/pages/rfc821.htm> 4.3 (and RFC2821 <http://www.dnsreport.com/tools/rfc.ch?detail=2821> 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record. MAIL.autosoldnow.com claims to be non-existent host ASNMAIL.autosoldnow.local: 220 ASNMAIL.autosoldnow.local Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at Wed, 17 May 2006 10:04:59 -0400 Douglas Jensen Douglas.Jensen@xxxxxxxxxxxxx <mailto:Douglas.Jensen@xxxxxxxxxxxxx> Voice (952) 402-9821 Fax (952) 402-9815 Network Administrator Scott Carver Dakota CAP Agency, Inc. 712 Canterbury Road Shakopee, MN 55379 www.capagency.org <file:///C:\Documents%20and%20Settings\djensen.SCDCAP\Application%20Data \Microsoft\Signatures\www.capagency.org> ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Andrew English Sent: Wednesday, May 17, 2006 8:37 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Reverse Lookup 2 Can someone check to see if autosoldnow.com reverse lookup is properly configured? It says on dnsstuff, and dnsreport that reverse lookup works but that it points to mail.autosoldnow.com, when I look up my other mail servers most of them point to there-IP.providername.com I am asking because emails are still backing up in Exchange. :( Regards, Andrew
