This looks like a sendmail problem, not a MailScanner problem. Try
         /usr/sbin/sendmail -d0.1 -d0.4 -bt </dev/null
and it will print out what it thinks its hostnames are. Something is very
wrong with the /etc/hosts or something else that sendmail uses to work out
its hostname.

You can also verify what it will try to do with a message with
         /usr/sbin/sendmail -bv address at domain.com
