Hey guys,

I have a network with 3 servers running on server2k.
My mail server is running exchnage 2k and lately i noticed a problem.
We have oour domain name let's say domain.com we r using to receive and send emails.
In my exchnage system manager when i'm looking at the queue i have a folder called:
Internet - domain.com(SMTP connector - Remote Delivery)
The email address to which the email in the queue are sent is fo@domain.com a address i never created and that i can't find anywhere in in active directory or exchange manager. This folder is also always full of emails, everyday more than a 100 emails that i delete with no NDR.
What is this address, how come i recieve email there, and how do i get rid of this address one and for all.

Thanx guys

I'm not really sure if I understand your question correctly.  I believe that it is your system generating trying to generate NDR's.  More and likely they are from spammers trying to send you spam and sent it to an invalid email address on your system.  The problem with spammers is about 80% of the time they spoof the messages with fake domains, so when your system tries to send a NDR it cant find the domain because it doesn't exist.  Exchange be default holds the message for a specified period before deleting it.  The reason it does is so that if an DNS server or an Exchange server is down for maitainence that the email will be requed and tried later.  Here lately with all the spam that is being sent through the internet this has become a common problem.

It really doesn't hurt anything being in your queue.  Those messages in your queue take up very little if any resouces on your server.  They should automatically time out and delete them selfs in 24-48 hours depending on how the timeouts are on your server.  You dont want to turn NDR's off all together because people do mispell email addresses from time to time and it may be an important message and the person on the other end thinks you have recieved it.  Those items in your queue are just part of running an email server.
