Spam filter settings for Weasel

Hi, everyone.

I'm thinking about firing up a mail server (POP3/SMTP) on my own system.  I'll have to use SMTP relaying since my ISP has taken the "wise" step of completely blocking port 25.  I'd like to use Weasel, but I really need a good spam filter on it.  Does anyone have any recommended filtering systems for use with Weasel?  Something preferably fairly easy to use?  :)

Thanks,
Sean

Well, I would recommend to go for a greylisting feature first; similar to what you find for other platforms. By this you will 1) block the vast majority of spam and 2) minimize the CPU load on the server. If I for example disable greylisting on our server; the CPU peaks to 80-100% all the time directly due to antivirus and spam scan activities.

In rare cases such as with Google; asking them to resend e-mails usually means that they resend from another of their outgoing mail servers and this confuses the greylisting since the initial blocking of incoming e-mails needs to be resent from the same server again.

I would say that using the combination of rexx and mysql any one with proper skill should be able to hack something together for OS2. The implementation we're using at OS2 World is a combination of extension to Postfix.

Following [urlhttp://workaround.org/articles/ispmail-etch/]How-To[/url] maps out how it works and should easily be portable to OS/2. Problem is that I'm not the one for that since I don't code. But, I would be happy to help out with testing such script under OS2. I think it's needed as well. Maybe a bounty project?
