I’ve been using POPFile <\/a>for almost a month now, and am very pleased with it. It’s an open-source message proxy that intercepts all the POP3 e-mail coming into any accounts I have and searches it for spam.<\/p>\n

Interestingly, the way it does this is simply by associating content words with either being spam or something else (you can create as many categories as you want, but I just do that sort of binary filtering). Not phrases — just words. (Yeah, I thought it was goofy, too, but, damn, it works.)<\/p>\n

Though you can force it to classify certain things as spam (by mailing address or parts thereof, or subject line words), I’ve found I haven’t needed to. Simply by providing feedback over time (“No, this <\/i>is spam, and this <\/i>is okay”) I’m presently at >95% accuracy (mostly false negatives about mail being spam) over the course of 1,100 messages during the month (i.e., including that learning period). That’s surprising and gratifyingly high. <\/p>\n

Looking at the stats, I can also see that about 16% of the mail I get here at home (vs. work) is spam. <\/p>\n

Since POPFile is a mail proxy, it’s usable with any POP3 client. It can be set to either modify x-header information or subject lines, so that your mail client can then push the spam (or other classification) into the folder you like. I still review what gets classified as spam (and vice-versa), at my leisure, but it’s trivial to do. <\/p>\n

(I do still use SpamAssassin through my host, but that usually just confirms POPFile’s judgments — it always targets the messages that SA identifies, but usually finds even more.)<\/p>\n

As an open source product, it’s free (donations are accepted), and continues to be improved and upgraded. If you’re looking for a relatively simple and quite reliable anti-spam product, and are willing to invest the initial training time, POPFile is definitely worth looking at.<\/p>\n","protected":false},"excerpt":{"rendered":"
