Somewhere, probably in /etc/mail/local-host-names, you told sendmail
that domain.com should be delivered locally.  Remove that entry and
restart sendmail.

If if was defined in /etc/mail/<HOSTNAME>.mc, then edit
/etc/mail/<HOSTNAME>.mc and restart sendmail with a "make all install
restart".

You can probably find the entry with a "grep domain.com /etc/mail/*".
