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@ pat@your-domain)
+ when from = null
+ when date > Date.Now
+ without To:


if you've got other ideas :o)

I use SpamBayes' Outlook Plug-in (obviously client-side). It makes Outlook
usable, again.

How are you using SpamBayes with James?

I've written a very very simple (it only reads alphanumeric characters) 
v**i***agra = viagra... but not yet v1@gra :o)

Content analysis... they send now picture... so there is no text ... do 
you want to analyse picture with text finding ? :o)
the war is lost.. we can just limit it :o)

Re: A good spam tool

I have real concerns about some of the techniques people are using to 
block spam.  Anything that blocks 100% of the spam is bound to block aq 
lot of legitimate mail.  Content analysis is one of those shotgun-like 
techniques that blocks too much of the good along with the bad.

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 v1@gra, 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.
