Hello all,

I have a problem with my email list messages being rejected by remote hosts.
20:37:18.994 1 DEQUEUER [13608339] SMTP(gmail.com)address@gmail.com failed: we refuse to relay

Initially, I thought this might be an SPF issue and updated our SPF record in the DNS.  No change.

Perhaps it was the way the headers appeared.
"Received: from [127.0.0.1] (HELO localhost.localdomain)
  by crossref.org (CommuniGate Pro SMTP 5.2.10)
  with ESMTP id 13607978; Sat, 21 Mar 2009 17:51:36 -0400"

Editing the hosts file to put the server IP and name in the first line did not change the behavior.
"Received: from [127.0.0.1] (HELO cr6.crossref.org)
  by crossref.org (CommuniGate Pro SMTP 5.2.10)
  with ESMTP id 13608028; Sat, 21 Mar 2009 18:12:55 -0400"

I changed Mailman to force it to use the host instead of the loopback. Still rejected.
Finally I reconfigured Mailman to use SMTP_AUTH and port 587 to send out mail.  Still it appears to remote hosts as if they are relayed messages.

I am stumped here.  Users do not have this problem sending messages directly to the users in the list.

The last failed message headers:

The IP's are Client IP ranged.

What is making this appear to be a relayed message to the remote host?

Thanks for your help
