Sendmail problem: "mail loops back to me (MX problem?)"

Hi. Having a few problems.

I've got the MX records for a number of domains pointing to a single host, and on that host I've put the domains in /etc/sendmail.cf, ie:

Cw stub.org

I've also tried putting them in /etc/sendmail.cw, but that hasn't helped.

All the FAQs stop there, assuming that this will solve the problem, but it hasn't. I'm still getting mails to this domain (and others) bouncing with:

----- Transcript of session follows -----
553 www.vx-labs.org. config error: mail loops back to me (MX problem?)
554 <ade@stub.org>... Local configuration error

What else could be wrong? (Yes, I have restarted sendmail)

Thanks in advance

Oo, I should mention some details:

Redhat Linux 6.0, hostname is root.vx-labs.org, running sendmail 8.9.3. The domain I'm trying to get working is stub.org

[root@root named]# cat /var/named/named.stub.org
@ IN SOA stub.org. root.vx-labs.org. (
2000021600 ; Serial
28800 ; Refresh
14400 ; Retry
36000 ; Expire
86400 ) ; Minimum
IN NS ns.vx-labs.org.

IN MX 5 mail.vx-labs.org.

IN CNAME www.vx-labs.org.
* IN CNAME www.vx-labs.org.

Hope this helps a bit.

Thanks.

Excellent, that's just it. Thanks.

I didn't realise that sendmail would look at the CNAME for the domain, I only thought it used the MX records.

It works perfectly now.
