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 *@ogh.org 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?
