Cool! Unfortunately the only way for me to try it would be on a production
server because I don't use M$ Exchange at home :)

Could several of these rules be used in the sendmail conf file because
Exchange will send out unwanted messages with the following subjects:

Delivery Status Notification (Success)
Read:
Not read:
Gelezen:
Niet gelezen:

I wouldn't want to silently drop any regular mail that must go through the
server.

Is blocking these kinds of messages on the todo list of features to come
:) :) ????
