I would recommend enabling Message Tracking and seeing what is happening, you could also use Netmon to do a trace on the SMTP traffic between the front-end and the back-end.

"Why would you do that?" some may ask since in BE and FE Excange topology you don't need the SMTP connector. Here is why: 1. I use to have BE and FE all running on win2003 with Exch2003 enterprise servers. My BE is clustered and FE hosted Microsoft IMF and OWA. Since IMF didn't do a very good job for our company, we looked into commersial software for Spam. 2. I am running a trial of ModusGate by Vircom. Since Spam software come with it's own SMTP setup, i disable all the SMTP and Exchange services on my FE server, but left OWA hostimng running. I also left the settings on the FE server checked for "this is a FE server" so the OWA will function correctly. So far everything worked good. I was catching tons of spam emails and blocking it. By later i discovered that i cannot filter anything leaving our domain, information moves freely out of the mail server. I had a feeling BE server no longer used FE server to send mail through. That is why i setup SMTP connector on my BE clusters to old FE server that runs Spam software. So far it hasn't been working, i don't think BE is using this connector to send mail through FE. Do any of you know if there limitations in 2003 Exchange? I had same setup in Exch5.5 and it worked fine, because i filtered all kinds of stuff. Thanks, Vadim. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: markfu@xxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
