I'm looking for an easy/cheap way to block spam from ever leaving my network.
With the uptick in virii/spyware lately, I have had quite a few spambots coming into the shop to get cleaned up. Some of them because the ISP has shut them down for sending spam. Once in a while (twice in the last month), one of these machines will get plugged into the network before it is 'really' clean and start spamming again. Luckily, I know the ISP guy that monitors this and he just calls and tells me to unplug it, but I would like to keep that traffic from ever getting out of the network.
I know I could setup an Untangle box to only allow smtp traffic from my Exchange server, but I also need to be able to allow smtp traffic to machines from time to time to test their email client configurations. Does Untangle allow for outgoing spam filtering instead of just blocking based on port 25? If not, is there anything else (preferably open source) that could do this?
Thanks for the suggestions
