<DIV><SPAN class=233594618-18102006><FONT face=Arial size=2>I have a number of
users that seem to get amnesia when trying to send email to other employees at
work. Specifically, they forget what the email domain extension is
assigned to our email system and end up sending messages that should be
going to our domain to another domain that is not associated w/ our company. Of
course, they're getting bounced but I would like to stop the messages from
exiting the system and bouncing off of this poor admin's email
system.</FONT></SPAN></DIV>

<DIV><SPAN class=233594618-18102006><FONT face=Arial size=2>Is there a way to
write a rule in MailScanner that would basically do this:</FONT></SPAN></DIV>
<UL>
<LI><SPAN class=233594618-18102006><FONT face=Arial size=2>Check to see if the
message is for a valid user (in terms of username) for our
domain</FONT></SPAN></LI>
<LI><SPAN class=233594618-18102006><FONT face=Arial size=2>Check to see if the
message has been addressed with an improper email domain (username@maildomain
.com instead of maildomain.net, etc)</FONT></SPAN></LI>
<LI><SPAN class=233594618-18102006><FONT face=Arial size=2>If both previous
checks are yes, bounce the message prior to it leaving the
MTA</FONT></SPAN></LI></UL>
<DIV><SPAN class=233594618-18102006><FONT face=Arial size=2>Is this something
that can be done w/ MS or should it be addressed by the MTA
(Postfix)?</FONT></SPAN></DIV>
