[RESOLVED] Might have a trojan, need help asap

Here is how to disable NDR entirely.

Open Exchange Manager | Global Settings | double-click Internet Message Format then right-click the Default format, select Properties then Advanced tab.

You have a list in there, one of which is the allowing of NDR.

You do need to consider carefully whether you want to disable them entirely. This means that a genuine expediteur who mistypes an email address doesn't receive a response to say so when the mail is bounced by your server.

For example, a client sends a mail to [email protected] it will get bounced but they won't receive a failed delivery report. Not always good from a customer care point of view.

I generally enable recipient filtering which cuts out a lot of the crap and live with the fact that a good volume of NDR produced will be from spam. It's a trade off in the end.

This is a fairly important part of the Exchange Manager if you want to allow out of office and various other features that are useful to the end-user.

As always with MS it's tucked away nicely out of sight!

Edit: I just realised you're running Exchange 2k; the steps detailed in the MS KB and what I mentioned above may be slightly different. I don't have a 2k box to check out at the moment.

From memory they should be pretty much the same.
