Mail Delivery Failure

[grayloon]

WHM 11.23.0 cPanel 11.23.3-R25048
REDHAT Enterprise 4 i686 on standard - WHM X v3.1.0

I have numerous domains setup with cPanel on my web server. This server doesn't host ANY email - instead, mail is sent to our smtp server for delivery. Several of our websites use PHP to send email messages, but one website is having trouble.

A typical PHP message in the exim_log looks like this:

2008-06-03 13:17:35 1K3b4h-0003Gw-Vk <= webmaster@grayloon.com U=nobody P=local S=599
2008-06-03 13:17:37 1K3b4h-0003Gw-Vk => cdavis@grayloon.com R=lookuphost T=remote_smtp H=grayloon.com.s5a1.psmtp.com [64.18.4.10] X=TLSv1:AES256-SHA:256
2008-06-03 13:17:37 1K3b4h-0003Gw-Vk Completed

The problematic site seems to want to handle mail locally. The log shows this:

2008-06-03 13:14:01 1K3b1F-0002Nq-MG <= nobody@138973-web1.www.grayloon.com U=nobody P=local S=779 id=e2736f7f5e96a1183ed1183417b229c9@www.kunkelgroup.com

You should check the mx entries on the server to make sure they are correct.

If all else fails manually move the domain from /etc/localdomains to /etc/remotedomains.

I just opened /etc/localdomains and found several domains in there. Should I move them all to /etc/remotedomains? BTW, I'm not running DNS on this server either.
