Carl, I thought this was a no-no and just invites directory harvest attacks?
"Reject messages to recipients not in the directory" Or am I thinking of something else?

Carl ________________________________ From: Thomas Gonzalez [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 20, 2008 11:36 AM To: MS-Exchange Admin Issues Subject: question about having two domains in exchange So, I've been working for the Girl Scouts for over 18 months and the organization is interesting. With that said, since I have been here, we had a domain (sagirlscouts.org) and this domain has been plagued with SPAM and at one point was relaying. The previous IT person was removed since the organization was blacklisted. Now we have a new domain and I do not see very much spam hitting that domain. However, upper management decided we should keep the old domain. I'm ok with that decision, however my dilemma is this: I have been monitoring all the packets coming into the exchange server, (one server, no front or back end) and the old domain is constantly being spammed hard. Is there some type of tool or different setup I can do to prevent the spam being forwarded onto the users? Management requested we have both domains appended, but this is stressing out the server. In a nutshell this is what we have: Exchange 2K3 SP2 Win 2K3 SP1 IMF enabled Trend Exchange Suite 8 TIA, Thomas Gonzalez Technology Manager Girl Scouts of Southwest Texas 210.349.2404 phone 210.403.1586 DID 210.349.2666 fax www.girlscouts-swtx.org [EMAIL PROTECTED] ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
