There are also another step that I had to call MS for. Here's what posted
previously that fixed it for me:
***********
Actually the MS rep called me back and had an answer for me. His system was
down earlier, i guess.
Follow the instructions below. Involves creating a registry value under the
IMC registry key, and then setting it to whatever you like. I wasn't too
clear on the more advanced options, I just used the first value which did
the trick for me. Create the value, edit it, and restart the IMC service.
Send your system an email to something like bogusaddress@domain.com. You
should find that it doesn't come back to you.

Subject: Hotfix to suppress NDR generation in Exchange 5.5 There is a new
hotfix that will allow Exchange 5.5 administrators to prevent the creation
and delivery of NDRs.
You can disable NDRs in Exchange 2000 and Exchange 2003...and now you can
disable NDRs in Exchange 5.5 too. Due to some of the recent email viruses
and worms, email is being sent to organizations that have invalid addresses
causing a lot of NDRs to be generated. This was bogging down the Exchange
5.5 IMS. This hotfix updates the Internet Mail Service and forces it to read
a registry value. This registry setting can be changed by the administrator
to any 1 of 4 options (see below) that allows them to control how NDR
generation is handled.
HOTFIX 837794 (bug # 240575)
Version 2658.3
msexcimc.exe & imcmsg.dll
Hi Tim,
Follow the instructions.
Registry description
-----------
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIMC\Parameter
s
Value name: SuppressNDROptions
Data type: REG_DWORD
Setting_________Result______________________________________________________
If enabled 0x0001, IMS doesn't send any NDR message out.
If enabled 0x0010, IMS don't created NDR message. This include two parts.
1> If send message to a certain test@bogus.com <mailto:test@bogus.com>,
1> the
rejected mail should be NDRed to the sender, this NDR message will not be
generated.
2> If receive a message, and the user address can't be resolved, NDR
2> will be
generated and sent back to the sender. Those NDR will not be generated. So
when this bit is set, bit ox0001 is useless, no NDR for IMS to send at all.
If enabled 0x0100, IMS doesn't deliver messages without SMTP return address.
This include NDR, DR.
More clarification on the settings:
0x0000 is NOT set
0x0001 is set - no NDRs are sent outbound.
0x0010 is set - no inbound NDRs will be received and no NDRs are sent
outbound.
0x0100 is set - no DSNs are sent including NDRs, delivery receipts (DR),
etc.
