Jason,

I would recommend go back to a default-deny policy as soon as possible.
I think that was our original XANSYS policy to not allow non-member
addresses. The Bayesian filter method can be relatively slow under
current spamming techniques. I can speak from first-hand experience.

Hey guys,

I've been messing with the spam filter. We've implemented a Bayesian
filter, which is essentially a learning algorithm. I've trained it with
ham (i.e., non-spam) from the archives and every time spam gets through,
I use that to train the filter. But it takes some time to learn and
filter effectively.

One alternative is to deny all posts from non-member addresses. That's
how the new server was set up initially, and it worked really well. Do
list members really post that often from non-member addresses? Would
anyone object to a default-deny policy?

Thanks,

Jason

I have started receiving a trickle of spam supposedly coming from the
xansys mailing list. Gotten 3 so far in the last 10 minutes or so.
Getting through the local spam filter too. Anybody else getting some
spam?

Regards,
Chris
