Alternatively you can download the latest stable version of this software.

SpamPal sits between your email program and your mailbox, checking your email as you retrieve it. Any email messages that SpamPal considers to be spam will be "tagged" with a special header; you simply configure your email client to filter anything with this header into a separate folder and your spam won't be mixed up with the rest of your email anymore!

But how does SpamPal know what is spam and what isn't? Well, it uses what are called DNSBL lists. Patterned after the famous MAPS RBL, these are lists of parts of the Internet that in one way or another facilitate spam. Any email you get from a machine on one of these lists has an increased probability of being spam. Some ISPs already block all email from machines on some of these DNSBL lists, but many do not. This is where SpamPal comes in.

You can choose to use any or all of the freely-usable DNSBL lists; SpamPal will look at the machines each email message passed through on its way to your mailbox, and if any of those machines is on one of the DNSBL lists you have chosen then that message will be tagged as spam.

Because not everyone who uses a machine on a DNSBL list will be a spammer, SpamPal has a powerful whitelisting feature that allows you to ignore DNSBL listings for certain senders or for parts of the Internet.

What's New:

The main bugs fixed are in the transparent proxy, in particular the bugs that were causing Thunderbird to crash a lot. If you're having problems with the SpamPal transparent proxy, I suggest upgrading to this version.

Also, for those using SpamPal as a Windows service, this version should fix the issue where it would occaisionally start looking for its configuration data in another folder.

Those using a beta-release of SpamPal, such as 1.72x or 1.73c, are advised to upgrade to this version. Those using the latest release build v1.594 should not upgrade to 1.73g unless you want to experiment with the new features.

As ever, I must remind people that SpamPal v1.73g is a beta-release and may still contain bugs. Please don't install SpamPal v1.73g unless you understand this and feel confident facing the risks that may come with using beta-releases of software.
