Stopping bad returned email address from a large mailing from being re-processed

I want to send out a email to 2000 of our agency's, However in the past someone sent out a email to them and had a 6 MG attached file. Because our database has alot of bad email addresses, My Exchange Server kept trying to re-send and re-deliver. THis took out my exhange server to a stand still b/c of the attachment.  IN THE FUTURE I want anything that comes back on first attempt to be deleted or go to a separtate place not to be re-sent at all. Last time it kept trying to re-send I even stopped the services and did the delmsgs=Sender etc from that specific user and I still had troubles trying to stop it. Can this be done ????? I

Doing this from Exchange is not going to be a good idea, infact, doing this at all isn't really a good idea, but we all have to do what we have to do i suppose.

Exchange will never try and resend a message that has bounced - if the receiving server gives a fatal error (like: Wrong email address) then it gives up.

I would be inclined to either use a mail relay service (ala, your ISP) or setup a Windows 2003 server by itself with SMTP installed.

If the error is "mailbox full", you'll have a temporary error and resend attempts, I think. I don't know if you can make Exchange give up on temporary errors; normally you want this resend function to execute until message is delivered. If there is a fatal error there will be no sending (as stated above) and you get a failure message (or possibly an NDR from the recipients' server).

It would be interesting to know what actually happened here. Perhaps it's a problem with the queue size; if you have like 500+ messages of 6 GB waiting, maybe something hits a limit?

I was under the impression that "mailbox full" errors are permanent fatals, so should not retry

I would have to test, as soon as I stop injuring myself with PHP ;)

This is exactly what happened. Someone sent out a large attachment in a email to about 2000 email addresses. I'd at least 25% are probably not valid addresses. My exchange server bogged way down, my internet line. to where I clicked on anything it was lagging. I noticed all the emails that probably were bad kept trying to re-send. I shut down the SMTP service and everything came back to normal from a while. THen I did the Setver, delmsgs=send etc for that specific users email address. However even thought I kept deleting them Exchange for some reason kept bringing them back and trying to resend out. I froze them, went in detailed message, Deleted with NDR. But they kept re-appears trying to go out. So I noticed there was hardly any hard drive space left, in the exchange server folder mdbdata there were about 100 logs with 6 mg attachement. So what I did was delete them ""BIG MISTAKE" I tried to bring back my server and nothing would mount. This was because the email server was in a dirty shutdown mode. After troubleshooting I called Microsoft. I had to do a Hard REpair, then off-line defragmentation, and then the isinteg command line. Once done re-merged Data Store, Merge new data with old to mailboxes and then re-mount and everything was fine. However I noticed now in the queue their was about 200 email addresses that were from the user who sent the file and I deleted them and everything was fine. SO there must be a way to stop the exchange server from re-sending. I played around with the Delivery Option in Exchange SErver Manager, but not finding anything I know would do this.

I doubt that is caused by resending them at all.  Sending 12GB of mail in one hit is never going to be a smooth transaction.

I would urge you to reconsider this.
