I've just sent out a new version of Trash Finder Pro. This version adds a number of new filters, including: * An SPF filter; this detects mail with forged return addresses (which is most of the incoming mail). If there is no SPF record, or the result is inconclusive, TF Pro will make a guess based on the mail-to servers. * RBL filters. Some RBLs are too aggressive (Spamcop has been blocking mail from IBM employees), but they can be used as a reason to trash and hand-inspect mail. Also, if you use an external secondary server, you can recheck the mail based on its real source. * HELO filters. Some spammers like to have their servers imitate yours. If you don't allow sending outgoing mail from outside of your network, blocking these imitations can get rid of a lot of spam. As above, you can recheck the mail based on its real source. * A filter for mail with unresolvable URLs. A common trick to avoid server IP filtering is for spam domains to fail to resolve until some time after the spam is sent out. (The idea being that the recipients of the junk will not read it for a while.) This filter prevents such mail from sailing through TF.
A number of filters were improved, including the "empty message" filter (which now triggers on messages that contain nothing but MIME headers) and the "no text" filter (which will now not trigger if there is text anywhere in the message). A number of new redirectors have been added. Limited filtering masks also have been added. These allow setting which filters will be applied (and which skipped) if various conditions occur: From, To, and Subject patterns, SPF Pass results, and messages relayed from the TF viewer. And, as always, a number of bugs have been fixed. As before, TF Pro is available by subscription of $50 per year; see http://www.rrsoftware.com/html/prodinf/tf/tf-pro.html for more information.
