Thanks Julian.  I'm guessing I can just change the port that trend will listen on via sendmail.cf since Trend calls that anyways I believe (ie, something like DAEMON_OPTIONS(`Port=26, Name=MTA')dnl

What about MailScanner?  Do I need to do it via Sendmail.pm or something? I looked through all the files but couldn't really find anything obvious.

thx
