Your server is claiming to be asnmail.autosoldnow.local when it tries to
send email. 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

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. :(

Andrew
