Non Delivery reports disappear at gwia

[smcilduff]

Thank you for your replies, MRosen was spot on with
"and if that can be disabled at the relay, I'd certainly do it."

So on my MSoft 2003 IIS SMTP sever I used Metabase explorer and found the following data under SMTPSvc/1:
ID: 36998
Name: SmtpInboundCommandSupportOptions
Type: Dword
Data: 7697601

I changed this to
Data: 7697537 (In hex deduct 0x40 from original data and place here in decimal)

Now, no matter what options are set on the client, the NDR gets to GWIA and then to the mailbox. Tested and confirmed.

This line is no longer appended to the NDR:
Original-Envelope-Id: groupwise.4AE66794.D71ec:570b:

Thanks also to this link
Enable/Disable ESMTP advertisement | onHacks
for the IIS SMTP info.


Regards and Thanks
