Global and per-user bayesian databases

Hi,

Our old environment used per-user bayesian databases, but now we've
decided to use one that is site-wide.

The thing is that some users managed to train their bayes filters quite
well and we don't want to loose it.

So is it possible to configure spamassassin to use both global and
per-user bayesian databases?

Or is it possible to import one database to another _without_
overwriting the second one?

Regards,

No

Not directly, but what you could do is use sa-learn --backup to dump
the individual databases into text files and write a simple script to
combine them. The format of the files is pretty straightforward.

hope thay have the ham/spam mails still, in that case its possible to 
relearn bayes from it

that will be a bug report for supporting it, bayes db is possible to 
migrade from pr user to global, but from global to pr user is more 
complicated bayes wide, here i have not tryed make a sa-learn --backup 
and --restore on another user, it might miss --restore-merge to do what 
you like to do

yes bayes is pr user so 2 or more users can use the single id user in 
user_prefs
