You would not want to disable NDRs in Exchange, even though they can get annoying. This is a critical part of the email system, and disabling NDRs on your server means it will not be conforming to SMTP RFCs (laws on how SMTP should work, basically). Breaching the RFCs can ultimately result in your server being blacklisted.

I would suggest that you take a look at why these Delay notifications are being generated, and what you could do with it. NDR reports for undelivered mail should not be switched off anyway; if a client tries sending an email to you and it bounces, do you really want no NDR report to be generated, resulting in the client never knowing their message bounced and your company ultimately losing out on potential revenue?

I know it sounds strange, and I do not agree with the situation myself, but my boss does not want to receive email telling him a message he has sent is delayed or even that it was not posible to deliver it.

I found a way to do it in Exchange 2007 but not in 2003.

I hope it cannot be done!

I am seriously uneasy with this. But, if you must, there is a way to turn off NDRs in Exchange 2003. I simply cannot reiterate it enough about how important having NDRs switched on is though - not just from a technical standpoint, but from a User standpoint too.

Anyway, Exchange 2003 can be stopped from generating NDRs by performing the following:
  1. Exchange System Manager
  2. Global Settings > Internet Message Format
  3. In the right-hand pane right-click the appropriate Format setting (probably the Default), and choose Properties.
  4. On the Advanced tab, you can check/uncheck the box to enable/disable Non-Delivery Reports.
Remember that this will only stop your server from generating NDR reports. If your boss is receiving NDR messages which are generated by another server, this will NOT stop these messages. He would have to have a rule to scan message subjects and delete anything which appears to be an NDR.

Please reiterate the issues I've mentioned to your boss before turning NDRs off company-wide - it sounds like it is no harm, but it could cause disaster in the future.

Many thanks for the points, and I'm quite glad there's another mail server out there conforming to SMTP RFCs!
