What is the most effective way to stop spam e-mail on a desktop? We have a peer-to-peer network, and our ISP also hosts our mail server, so I need to set this up for each machine.
One of the best free solutions is SpamBayes (spambayes.sourceforge.net), which integrates directly with Outlook or works with any POP3-compatible email client to stop spam.
Microsoft also has a plugin for Exchange that combats spam based on statistics and rules generated by analyzing millions of emails filtered through Hotmail.
