How to detect a spammer on your network? What to do about it?
The mechanics of detecting a spammer on your network is fairly straightforward. Spammers will spam via your network in two ways: (1) Via a compromised host on your network. An infected machine has become a bot in a botnet and is sending out spam directly to the internet. (2) Via a compromised mail account where the spammer will be using one of your user's mail accounts to broadcast spam via your own MTA. (May 31, 2011)
