It shouldn't cause anything bad. Now instead of using resources on trying to send those NDRs the resources will be used on the Exchange server and on the GC running LDAP queries for every inbound message that hits the Exchange server. I am not sure if it is a 50-50 trade-off. But if anything, you won't have a ton of bad messages files in the queue.

But thanks... everything seems to be working now. I also found out the answer to my previous problem #1 how do reduce the amount of stuck NDRs. In Exchange Manager\Global Settings\Message Delivery Properties\Recipent Filtering There is a check box that says "Filter Recipents who are not in the directory." Turn that on then go to the SMPT Virtual server Properties\Advanced\Edit\Apply Recipent Filter Then stop and start the SMTP service. The E2k3 server should now reject all email to users who don't exist in AD before it generates a NDR. In the default config E2k3 will accept email to any name (in the domain) and then generate an NDR after, if that name does not have a mailbox. Right now Spoofed Spam NDRs are tying up resources on my server trying to deliver NDRs to sites that don't exist. My disclaimer is... Microsoft Support informed me of this filter option and I can't say for sure it works as described. But I turned it on and if anything bad happens I'll post it.

Imagine a Yahoo smtp server trying to deliver a message to your Exchange server. How possibly can a Yahoo mail server authenticate against your AD? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
