using a global bayesian database?

[Roy Sigurd Karlsbakk <ro...@karlsbakk.net>]

hi

I've  started to train SA with some old mail (running slowly), and, 
running this as root, SA generates the database under 
/root/.spamassassin/

Can I have spamassassin update a common database for all users on the 
whole system somehow?

thanks

roy

OK,

It looks like I forgot to mention that you also have to change the permissions
on your global directory so that it is also world writable.

I don't use procmail, I use postfix with cyrus imap, but postfix can be 
set up to pipe through spamassassin so that's fine

thanks

I just tried, but it loks like the bayes_* files aren't updated :(
see below

Actually, it it entirely possible to use a global bayes database if you use
procmail. Just add these lines to your /etc/mail/spamassassin/local.cf file:

use_bayes               1
bayes_path              /etc/mail/spamassassin/bayes
bayes_file_mode         777

Also make sure that everyone uses the '-C /etc/mail/spamassassin' option on
sa-learn, so that they update the correct database.

One big advantage of this configuration is that while the common database is
the default option for all users, any user can override this and use their own
private database if they want.

This depends on how SA is integrated with your mail server.
if all incoming mail is run under the same account, then you have a a
global database, if it runs under each user, with procmail for example
then you do not.
their are many sa+mta solutions that allow this, I for example use
SA+mimedefang, which allows a global database.
Just check look up the different integration methods for SA that work with
your existing mail server.
