Although I think you're trying to solve a wetware issue with technology
(which is never an optimal solution IMHO), I think what you're looking for
should exist on GFI or McAfee's products.  You basically want to do away
with spoofing at the gateway to your mailsystem.  Check out their helpfiles
for configuration options.

Running Exchange 2003 on Windows 2003 in a 2003 Active Directory domain, OK.

I split up the mail flow into and out of our system in this way; We use 2
incoming gateways which funnel mail through GFI's Security & Essentials
along with MacAfee for anti virus & spam control.

Outgoing mail utilizes a different path, it flows through a different SMTP
server not visible to the outside world.

What I now want to do is to siphon off all incoming mail with a return
address that would make it appear to be coming from within. In other words
my adx is dstelley@xxxxxxx, I want all mail coming from the outside with a
return adx of * to be redirected to either a folder or a mail
enabled public folder.

I'm tired of questions from my users like: "I got an email from Joe telling
me to open this zip file but it has nothing in it, he says he didn't send
any, what should I do?"

We have no users sending mail except from within the Exchange community, no
POP3, no Outlook Express. Outlook & Web mail only.

I figure if I don't allow mail from joe@xxxxxxx allowed in, I should cut
back on a lot of headache.

Question, do-able? Does it make sense?
