-553 MX list for domain.net points back to relay.domain.net
-554 &lt;user@domain.net&gt;... Local configuration error

-How can I solve this problem?
-
-You have asked mail to the domain (e.g., domain.net) to be
-forwarded to a specific host (in this case, relay.domain.net)
-by using an MX record, but the relay machine does not recognize
-itself as domain.net. Add domain.net to /etc/mail/local-host-names
-[known as /etc/sendmail.cw prior to version 8.10]
-(if you are using FEATURE(use_cw_file)) or add <quote>Cw domain.net</quote>
-to /etc/mail/sendmail.cf.</programlisting>
