restricting email through exchange

Look on the Internet Mail Service...I thought there was a way to block an IP address....

Hope this helps a little

Unfortunately I don't know the ip address for these emails. Is there a way to find out? I have been going by each user, but it seems there's got to be a quicker way. Thanks,

There may be a better way, but here's what I'd try: Create a Custom Recipient in the Global Address List and give it one of the SMTP addresses you want to block. Click the e-mail addresses tab and add the other SMTP address(es) you want to block. The go into the "Reject Messages From" IMS settings and add the Custom Recipient you just created in the Global Address List. From now on, you should be able to block additional SMTP addresses simply by adding them under the e-mail addresses property of that same custom recipient. You probably also want to hide that custom recipient from the address book to save having to explain it to your users. Don't do it until you've set the message rejection, though, or you won't be able to see it either. Hope it works.

I created the custom recipient and added a couple test email addresses to them. Then I went to the IMS tab and then to the delivery restrictions tab. I selected the custom recipient, but am still able to receive email from that address. Any suggestions? Thanks
