This is both a BIND and a Sendmail issue.  Once you translate the name
to the IP address of acad3, the mailer should be reconfigured so that 
it knows that acad3 is LOCAL.  If you do not fix this problem, sendmail
will sense a loop returning errors of "I refuse to talk to myself".  Below
are excerpts of our sendmail.cf rewrite rules and named zone files required
to do this at our site.
