[cobalt-users] relaying denied, single domain on server

["t (dot) jay fowler" <tjay@xxxxxxxxxxx>]

Hello,

I'm getting this error:

Relaying denied. IP name lookup failed

when I send from my network.

and this erro when I send from outside my network:


Relaying denied.
 Please check your mail first or restart your mail session.


This is only on one domain on my raq4r. I'm tailing the mail log, and 
sending emails to many domains on the server, and this is the only 
one that gives me this error.

I looked through the archives and based on what I saw there tried:

Deleting and re-adding the domain
Running Meta-verify

I'm sending these emails through another SMTP server (not the machine 
hosting the domain).  There are reverse entries for all domains 
involved, verified through dig and nslookup.

Any ideas?
