Question : Exchange 2003 NDR email question

Hi,

SCENARIO: Exchange 2003 Ent servers  - Outlook 2003 clients

PROBLEM:

We are being bombarded with incoming NDRs from external domains due to spam.

The NDR email has the following format:

subject:
Delivery Status Notification (Failure)

Body:

Note: Forwarded message is attached.

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

      satellites4201@rivercoursegolf.com

Final-Recipient: rfc698;satellites4201@rivercoursegolf.com
Action: failed
Status: 6.7.2

QUESTIONS:

1.) I was wondering If for the time being I can block the inbound emails that contain the following subjet line:

Delivery Status Notification (Failure)

Or is that a pretty common NDR subjet.

I have tried to email to non-existent users/domains and I got the following message at the subject:

Undeliverable: test

2.) If we get an NDR wouldn't be getting NDRs from our internal SMTP server? Or are the external servers the ones that will send the NDR?

Okay - so Postini is passing on NDR spam to you!

Time to ditch Postini and look at an alternative if you ask me.

How much is Postini costing you a year to use if you don't mind me asking?
