[Q] How to prime Bayes with SA under amavisd-new?

[Rudi van Houten <R....@math.uu.nl>]

Hi all,

I am in the process of moving from postfix with 3000+ filterrules to 
SpamAssassin under amavisd-new. I already run amavis for virus 
scanning. My test configuration runs nicely, only the Bayes filtering 
doesn't start:

debug: ignore: test message to precompile patterns and load modules
debug: using "/local/perl5/share/spamassassin" for default rules dir
debug: using "/local/perl5/etc/mail/spamassassin" for site rules dir
debug: using "/local/amavisd-new/.spamassassin/user_prefs" for user prefs file
debug: bayes: no dbs present, cannot scan: 
/local/amavisd-new/.spamassassin/bayes_toks
debug: Score set 1 chosen.
debug: Initialising learner
debug: bayes: no dbs present, cannot scan: 
/local/amavisd-new/.spamassassin/bayes_toks

I expect that I must prime the Bayes database with spam and non-spam 
messages as I did with bogofilter. But I couldn't find how to do 
this. I presume I have to compile amavisd/amavis/spamd etc to get 
sa-learn, that was not mentioned in the amavisd-new INSTALL documents 
and the CPAN spamassasin installation. But even then it is not clear 
to me what I have to do. Can someone point me to documentation I 
missed?

with thanks

PS
The module DB_File was installed in /local/perl5/.....

As documented in the amavis .spamassassin/user_prefs file bayes doesn't work 
until it's been fed 200 spam mails and 200 ham mails. You need to feed them 
via sa-learn called by the user amavis runs under, in my case 'amavis'. Can't 
remember where I read the documentation about that, maybe in the list 
archives, which are a useful resource.
