An updated verison of SpamFilter ISP v2.1.1.367 is now available as a free download. As always, the free version is a fully functional copy, it has no expiration dates. The only limitation is the same as in previous versions, in that the web interface will not be able to force delivery of emails. The improvements since the previous free build 2.0.1.302 are as follows.
