well, you are writing to the netfilter coreteam (rusty,marc,james,jozsef

The major problem with this is that the mailinglists are hosted at samba.org,
and none of the netfilter core team members has more than a regular user
account.  So all I could do is ask the samba.org administrator to 
install Spamasassin.

However, tuning+configuration of spamassasin would then be in his hands,
and I don't want to have any filtering system outside the control of the
netfilter core team on our mailinglists.

I am _very_ sensible to content-based filtering.  It's a somewhat religious
issue and I don't even use content-based spam-filters on my personal email.

This issue is getting worse, if I am not talking about my personal email,
but about a public mailinglist. Who am I to censor what other people
receive?  

The only preconditions under which I would do content-based filtering
on any of the mailinglists I am admin of:

1) full control of the filtering rules
2) recognized spam is sent to the list admin, and the list admin is
   able to review the messages.
3) the list admin can 'approve' recognidzed-as-spam messages and
   manually send them to the list, without any filtering applied.

As I don't want to put the burden of installing and configuring such
a filtering system onto the samba.org admin (remember, we're a guest
at samba.org), there's only one solution:

- move the mailinglists to a dedicated machine under full control of 
  the netfilter core team

Normally I would offer to host the lists at my gnumonks.org site, where
CVS, FTP and one of the netfilter homepage sites is located.  However,
FTP and WWW are already causing about 12GB / month.  The estimated 
traffic of a high-volume list like the netfilter list is just too much
for my internet connection.

I'm working on getting a sponsored rackspace incl. all trafic at a local ISP,
where a couple of friends are working...  I estimate more news on that
during the next week.

If this would work out, I'd still have to buy a machine, install and 
configure it, ...
