Guide Review - Mailshell Anti-Spam Desktop 4.0 - Spam Filter

Good old scoring spam filters are nice, but a network that can check each message against known spam in real time is great, too.

Mailshell Anti-Spam Desktop tries a hybrid approach, combining the two. The results are mixed. On the one hand, Mailshell Anti-Spam Desktop does identify a good deal of spam and marks it flexibly in the Subject or in a custom header; working as a POP proxy, Mailshell Anti-Spam Desktop can be used with most email clients.

On the other hand, the filters are not transparent or customizable, and even in combination with Mailshell Anti-Spam Desktop return a number of false negatives as well as false positives.

Unfortunately, you can't submit classification corrections to the network with Mailshell Anti-Spam Desktop. You can, however, use the internal Bayesian filter to improve your results.
