A lot of NDR from postmaster / system administrator   

Hi

I have an Exhcange 2003 SP2 on a Server 2003 SP2 standard machine.

We have Trend as our anti spam/virus motor, with IMF (lates).

This easter a few users got lot of NDR from Postmaster and/or system
administrator, telling the users that some of the messages coud not
reach some/all resipients.

I was woundering why some of the users got over 700 message of thees
types? And what to do so that thy dont get these messages in the
future :)

Not sure what else to put in this post, but if you feel that you
should have more information, I can get it... just let me know what
you want ;)

Regards

Forgot:

It looks like "someone" is trying to send out spam from our Exchange
server. That is some of these users keep getting Mail Delivery System
messages, that says they cant send out thise message due to security
policies etc.
