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.

Subject: [exchangelist] SMTP connector not doing it's job

Hi guys,

I just setup SMTP connector on my BE clustered Exch2003 servers to route
all email for entire organization to my FE server. "Why would you do
that?" some may ask since in BE and FE Excange topology you don't need
SMTP connector. Here is why:

1. I use to have BE and FE all running on win2003 with Exch2003
servers. My BE is clustered and FE hosted Microsoft IMF and OWA. Since
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
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

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
runs Spam software.
So far it hasn't been working, i don't think BE is using this connector
send mail through FE.

Do any of you know if there limitations in 2003 Exchange? I had same
in Exch5.5 and it worked fine, because i filtered all kinds of stuff.
