Re: smtp error 4.4.7

you may be correct...got this from dnsreport.com:

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 4.3 (and
RFC2821 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.northcoastseafoods.com claims to be non-existent host
exchangesrv.northcoastseafoods.com: <br /> 220
exchangesrv.northcoastseafoods.com Microsoft ESMTP MAIL Service, Version:
6.0.3790.3959 ready at Wed, 11 Feb 2009 14:58:29 -0500 <br />

Try creating an smtp connector to that domain. Do not use DNS but
specify their mx server IP. Get the mx server IP from third party
source on net not from a query on your box.

then this might be a DNS issue...whose DNS are you using? have you tried
doing an nslookup for mx records for any of these domains?

Does anyone know how to eliminate this error?

We are using Exchange 2003 with Windows Server Standard 2003.

I am looking for a solution to this problem ASAP.

I have tried several fixes and none have had success

Since I am at the other end of this problem ( I am one of the exchange
servers northcoastseafood is having issues with) I thought I would
jump in. I think this is a reverse dns issue, since your system
connects to ours as exchangesrv.northcoastseafoods.com, but your mx
record is mail.northcoastseafoods.com. And the reverse dns is
mail.northcoastseafoods.com, so when my system trys to do a reverse
dns lookup for exchangesrv.etc, it fails and the connection is
dropped. I think correcting this would resolve the problems we are
experiencing.
