Why not just whitelist mail _from_ your mailman server (so you only scan
in one direction).  If you really want to minimise delay you could even
run a second sendmail (or other MTA) daemon (on an alternative port?)
firewalled to only accept mail from the mailman server and to send it
straight out without even having to wait for MailScanner to pass it
