I know about Exim, don't know about Sendmail or 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, ... > Best and thanks for the list - not to speak of the work you do on > Netfilter :c) You're welcome > Tony -- Live long and prosper - Harald Welte / [EMAIL PROTECTED] http://www.gnumonks.org/ ============================================================================ GCS/E/IT d- s-: a-- C+++ UL++++$ P+++ L++++$ E--- W- N++ o?
