[cobalt-users] Relaying Denied when delivering to domain on RAQ3

[Albert Meyer <cobalt_users@xxxxxxxxxxxx>]

I feel a bit silly asking about this because I've seen it discussed before, 
but I spent some time searching the archives and I can't find it. Will 
someone please post a link to the solution for the "Relaying Denied" 
problem? This isn't the one where people are trying to relay through the 
box, it's the one where mail comes in for a domain that is on the box, from 
another mail server, and gets rejected with "Relaying Denied." Here's the 
SMTP error message:

>Your message cannot be delivered to the following recipients:
>
> Recipient address: info@xxxxxxxxxxxxxxxxxxxxxxx
> Reason: Remote SMTP server has rejected address
> Diagnostic code: smtp;550 <info@xxxxxxxxxxxxxxxxxxxxxxx>... Relaying 
denied.
Please check your mail first.

Again, this person is NOT trying to relay through the RAQ. This is a mail 
server attempting to deliver mail TO the RAQ. The huntingleasesonline.com 
domain is hosted on the RAQ3. Here's what the maillog shows:

Jul 15 15:44:56 raq3 sendmail[1958]: PAA01958: ruleset=check_rcpt, 
arg1=<dean.clapper@xxxxxxxxxxxxxxxxxxxxxxx>, relay=nyssa.swt.edu 
[147.26.10.11], reject=550 <dean.clapper@xxxxxxxxxxxxxxxxxxxxxxx>... 
Relaying denied.  Please check your mail first.
