Guide Review - InboxCop Anti-Spam 9.2.4 - Spam Filter

Version numbers of software projects can mean a lot, and this includes very little. In InboxCop Anti-Spam's case the high number hints at a dated interface, but also at some feature-richness. InboxCop deals with many types of email accounts from POP over IMAP to AOL or Hotmail, and it filters spam transparently working as a proxy between email program and server.

Unfortunately, filtering can be slow (especially if you have InboxCop check the online spammer blacklist), and it is not always accurate, producing a tad too many false positives. While there's no obvious way to train the included Bayesian statistical filter, you can submit wrongly classified email for filter improvement easily. Reviewing and recovering caught spam is a snap, too.
