RE: IMC originator
Discussion direction 1. Not without unwanted side effects. Discussion direction 2. I time-out messages quicker than three days, because the attorneys are impatient. Imagine that. But then you don't have to look at them for as long. I can ignore them as long as I want, without blinking even. Discussion direction 3. Okay, so you can make a bear dance too, but would you want to? (pilfered from FAQ) Discussion direction 4. Implement various anti-spam measures that will also kill valid business-related messages. The other different directions this discussion can go in are beyond the scope of my laziness. Also, my coffee cup is empty. -Original Message- From: Alverson, Thomas M.

RE: IMC originator
It depends what bad spammer email address means. If the part of the address to the right of the @ sign truly does not exist in DNS (e.g., zjeorheorejreohre.net), then it should get thrown away very quickly as soon as the queue is processed. However, if the part to the right side of the @ sign exists, and points to a server that is really up (e.g., hotmail.com) but the left side is bogus, then the message will hang around until it connects up and either gets an error during the SMTP protocol or is accepted and deleted later. There is no way for Exchange to know that this NDR is destined to a bad spammer email address, while another NDR is destined for your grandmother who mistyped your email address. -Original Message- From: Alverson, Thomas M.

I delete them when I see them in the queue, but It would be nice if you could make exchange give up real easily (quickly) when trying to send an NDR to a bad address.

We've gone round on this before and it seems that server can optionally deny the message up-front or accept it and than NDR it back to the sender. Exchange does the latter. - Original Message - From: Siegel, Richard [EMAIL PROTECTED] To: Exchange Discussions [EMAIL PROTECTED] Sent: Wednesday, January 09, 2002 1:55 PM Subject: RE: IMC originator Ok, but they should not be sending ndr's in response to notification messages is my point.
