Hi,

is there a way I can stop our Exchange Server 5.5 email server from sending out NDR's to the Internet?

Many thanks ...

Doubt it, but you probably will get a better response if you open a new case and offer some points.  I don't really answer here anymore.

I'll do this last one for you though.  :)

Why do you want to keep NDRs from going to the Internet?  If you do stop them for any reason other than something like spam or a virus attack, then you won't be compliant with Internet Email standards (RFC 2821).  There are ways to do it, some difficult, others requiring 3rd party tools, but nothing off the shelf.  Tell me more about what you're after and I'll do my best to answer your question.

Thanks mate! I just wanna stop NDR's from going out from our exchange server, these are being generated from incoming virussed emails (payload stripped) to users who don't exist in our organisation ... hemce our exchange server is sending out NDR's ...

I see.  Well, you really don't want to stop NDRs, even  though you think you might.  :)

If you stop NDRs, you'll have an email system that doesnt play nice on the Internet.  It may even be considered hostile to some standards based purists.  One problem you will encounter is that someone will send an email to someone on your system who won't get it.  This could be due to a misspelled name or temporary configuration problem.  The problem is that the person who sent it won't know it and think you got it.  This can result in the perception of being ignored or even a lost business deal.

The best way to do what you need done is to do it through your anti-virus application.  Personally, I prefer to send the NDR.  I do, however, employ a directory above my viruswall to make sure that messages sent to invalid recipients are returned as such.

Probably not the answer you were looking for, but it is the right answer.  :)
