Those of us who manage the the mailing lists are overloaded
enough as it is.  We don't have time to add extra tasks to our daily
checklists.  In addition, ad hoc solutions frequently don't scale well.
Check for the full scope of the management problem.
We run a single SpamBayes instance on which scans for spam
in almost all those mailing lists.  A couple are unfiltered for various

If you read python-list via Usenet (comp.lang.python in its various guises)
there's not much we can do to help you.  If someone posts crap via Usenet
you will see it before it reaches the spam filter on  Some
Usenet servers may provide decent spam filtering.  Google Groups appears not
to, and their spam reporting process requires several steps on your part.
If you are reading python-list at please feel free to mail me
(skip at any spam which sneaks through SpamBayes.  I will train them
as I can, generally about once a day.  It would really help if you could
attach a zip'd or gzip'd copy of the message.  Don't just paste a spam
message into any mail you send me.

If you read email you get spam.  That is an unfortunate fact of life today.
You should run some sort of spam filter on your system and not rely on
sysadmins or mailing list admins to filter your mail.  My email goes through
Gmail and I run SpamBayes on my laptop as well.  That presents its own set
of issues (I have to poke around in both filters' traps to find spams which
sneak through the filters for example), but I generally see
very little spam.  You can get SpamBayes (it's free and written in Python)
from <>.  There are a number of ways to use it,
including an Outlook plugin and several more Unix-oriented apps.  All use
the same core classifier.  There is a Thunderbird plugin available (google
for ThunderBayes) which is currently unsupported but which we would like to
incorporate into the SpamBayes code base.  Unfortunately, we are short of
round tuits.  If you'd like to help we can always use more brainpower.
