Guide Review - Lyris MailShield Desktop 3.1 - Spam Filter
Lyris MailShield Desktop uncovers a lot of spam using a fuzzy logic scoring system, but usually leaves legit mail alone.
MailShield Desktop comes with a configuration that works great out of the box, but you can also tweak spam detection settings or submit spam to Lyris for analysis and further filter improvement.
Automatic filter updates via the net would make a nice addition, though, and MailShield Desktop doesn't achieve the accuracy of Bayesian filters. MailShield Desktop can take different actions for different levels of spam points, from marking to deletion and bouncing or forwarding to another email address.
Optionally, MailShield works as a POP proxy, making sure no spam can escape, and it also makes for a nice mail checker supporting POP, IMAP, MAPI and Hotmail accounts.
