I already have my firewall set to block this port traffic.  I use Scanmail
e-manager.  Should I then set a rule to delete any messages with the "ymsgr:"
in the content?  And what can folks suggest for internet filtering?  Exchange
2000/W2K.  I don't want to set up a bastion host mail solution with either
procmail or sendmail.
