One of the most promising techniques, to me, is graylisting (http://projects.puremagic.com/greylisting/). It won't block any mail from properly configured legitimate mail servers while increasing the processing costs of any spammer who wants to circumvent it. However, given the way James works, I can't see any way to implement a graylisting mailet. If I'm wrong, I'd appreciate someone setting me straight before I waste time building a filter in front of James.

Thanks for the quick response.
If everyone is writing their own, that's fine. Is there a sharing repository where people can contribute what they have so others don't need to reinvent the wheel?
You have some good criteria here. But content analysis seems to be missing. Have we thrown in the white towel on trying to write an algorithm to figure out [EMAIL PROTECTED], etc.?
Seems there is a market for killer matcher that keeps up to date with all the latest tricks. I'd pay a nominal subscription fee just like I pay Norton to keep my virus defs up to date.

Subject: A good spam tool
Hello,
I think there is no good anti-spam tool... so I developped it by myself...
We need to identify which mail is really a spam mail !! If any doubt, we
can't refuse it...
Here are my rules (for the moment) :
+ blacklists servers (James defaults + bl.spamcop.net)
+ I've got my own list of "forbidden froms" that I update every day... (@doubleclick, @.... )
+ When more than 2 local users does not exist in the recipients (spam mails usually go to james@ sam@ [EMAIL PROTECTED])
+ when from = null
+ when date > Date.Now
+ without To:
if you've got other ideas :o)
