You have to accept email from everyone if its your corporate mail server. That's how Email works.. Now to filter those connections.. You need to turn on RBL Block lists and use Zen.spamhaus.org Bl.spamcop.net (optional) Here is a good place to start with the built in mail filtering tools for Exchange 2007 http://www.msexchange.org/articles_tutorials/exchange-server-2007/security-message-hygiene/exchange-server-2007-spam-filtering-features-without-using-exchange-server-2007-edge-server.html Otherwise you need to look at spam filtering on the server or hosted. The list server host has a good program, but it takes resources and loads directly onto your server. Search the archives there are lots of posts on the subject.

Hi, I have Exchange 2007 SP2 RU5 with all roles on a single server except EDGE on a different server on DMZ separated by an ISA. Lately users are getting as lot of self send spam. So after googling, I removed Ms-Exch-SMTP-Accept-Any-Recipient from the EDGE server using the below command. The spam stopped. But users using Black Berry started complaining. How can I strike a balance between both stopping self send spam and allowing users to use Black Berry to send their mails. We don't have a BIS. Any help appreciated.
