I have a little trouble following the technical terminology. Could be that
I'm just on the wrong side of the pond however :)
What does 'duff addresse's ' mean? Is this an invalid recipient? If so,
why is it trying again? Maybe I'm misunderstanding what's going on?
If you're going to send a large amount of mail like that, might I suggest an
alternate delivery server for such email? A Windows 2000 server is a fine
server to do the job as is Windows 2003. It's just sending that you're
concerned with and nothing fancy based on your description. What you will
still have to contend with is the NDR's. Those will go back to the domain
they were sent from. In your case, possible stopping the queues. I would
suggest a timed delivery in that case so you can at least have all of the
NDR's come in over night.
The same timing might alleviate the need for a separate server altogether,
but either way has worked in the past where I've seen it. I prefer the
alternate server though. You never know how long it will take to send the
messages and it wouldn't affect production until the NDR's started coming
back.
100,000 messages aren't that many necessarily, so probably one server or
laptop would likely do it.

Subject: [exchangelist] Large Mailshot (not spam) causing problems with
regard to everyday urgent business e-mails

Hi Everyone,
The problem:
I freelance Sys admin for quite a few small businesse's, Using Ms Small
Business Server 2000. One of my clients needs to send out large e-mail
shots 50 to 100,000 e-mails (not spam but genuine offers to thier
customers). The problem seems to be caused by duff e-mail addresse's within
thier mailing lists. mail goes out ok but as to be expected duff addresse's
get returned ,wherby the server tries to re-submitt these duff addresesse's.
This is causing the following problem: Urgent/everday e-mail is being
seriously delayed eg. sitting in the que behind the mail waiting to be
re-submitted.
Re setting mail priorities and delivery timeouts does not seem to help and
short of deleting the mail que, I havent managed to resolve this problem.
Any advice or help would be much appreciated, I have had a good look at the
archives but have not found anything that seems to address this problem.
In anticipation.
Best regards.

As a footnote: When the que is finally completed mail delivery reverts back
to normal and all is well.
Info: all mail is sent using DNS/SMTP directly, dns is working fine.
