I've been trying out SpamFighter (spamfighter.com) and it's pretty awesome.
The main differences between SpamFighter & Mailwasher are....
Mailwasher:
I have to manually add domains to the blacklist any time I get a spam from a new domain. I add an average of 50 new domains to the blacklist every day, (and my list is a mile long now after using this for years)
Mailwasher runs as a separate program from the email client.
Mailwasher checks your mail on the server BEFORE you download anything to your computer.
Any domains or individual email addy that you blacklist or whitelist are unique to your system only.
SpamFighter
Integrates with your mail client.
Downloads email to your system first. Can't see the email on the server first.
Also can blacklist individual addys or domains at will. Addys you block/ban go into their system and are also blocked from every other user of the program. This results in virtually ZERO spam coming through to you because the more people that use the system, the better filtering there is. Sort of a collective filtering.
When first installing it, it's a good idea to go through your contacts and old emails and whitelist every addy and domain that you WANT to get email from, because after I installed it, I sent a test email to myself, and it didn't come through. Which means, I'm in their system as a spammer. I know what the reason for this is. Some spammer asshole has been forging my domain headers and spamming as me, using my domain. The downside to this is, anyone else using SpamFighter will not be getting my emails unless they whitelist me. BUT, I still believe this is the best spam blocking program I've ever seen. But users of it need to be vigilant in whitelisting their contacts.
it's an excellent blocker in my opinion. It has nearly completely eliminated spam coming through to me.
