broken relay

[mufka]

I have a server with Sendmail 8.11.6 on Redhat 7.2 and a few DNSBL's. I
want to use the server to filter spam and forward the mail on to the
destination server. I have found that I am getting "user unknown" errors in
the logs when a message comes in and it is not being forwarded.

In the access file, I have:

domain.com RELAY

In the mailertable, I have:

domain.com ESMTP:[mail.domain.com]


I noticed that the log shows domain.com and the ip address for domain.com
(which is not a mail server) as the relay.

I have never had this problem with 8.9.3. I have it working the same way.

This is a sample of the log I am getting.

Jun 7 15:23:00 spamfilter sendmail[23778]: g57JN0x23778:
from=<yippie@yahoi.com>, size=865, class=0, nrcpts=1,

Jun 7 15:23:00 spamfilter sendmail[23780]: g57JN0x23778: g57JN0x23780: DSN:
User unknown

Thanks for any help.

If I delete the DNS record for domain.com, I now get &quot;mail points back to ...&quot; it looks like it is not reading my mailertable. What could cause that? And why does it care what domain.com points to if the MX record points to my relay server.
