Spam blocking help neededHey everyone,
We are running Exch. 2003 ent. w/sp2 in a cluster with two FEs on Windows 2003 sp2. I need to know if there is a way to stop people from replying to emails. Example: Being that we are a Univ. we get a lot of "Phishing" email come acrossing our servers trying to get people to give their usernames and passwords. We would like to be able to put the "Reply" address in some kind of block list that would not allow anyone to reply to that address. Anyone know of a way to do that? TIA, Clayton The best option would be to filter out the spam/phish before it reaches the
users. I'd look at a gateway that can filter mail before it hits your environment - Forefront (from MSFT), Barracuda, something along those lines.

Thanks for the tip! I just called Barracuda and they said we *can* do it through the Barracuda if we send our outbound emails through the Barracuda (which we don't). Anyone else have any other ideas?

They usually include a clickable link in the message that takes the user to a compromised web site where the data are collected and, sometimes, nice packeges of malware are deposited on the dupe's machine. OTOH, lots of "419" mail depends on email replies (see http://www.419eater.com). The way to deal with this is to use a URIBL on inbound mail that checks the domain names in the links against a database of known spam/phishing/whatever domains. On the outbound side you want to filter your outbound web traffic and prevent it from reaching the compromiseds sites. --- Rich Matheisen MCSE+I, Exchange MVP
