Re: Tips on training bayes?

Hi
I was very disappointed with spamassassin 4.x because it started to grow 
/var/lib/amavis/tmp/

With SA 3.4.X - on average 100MB and it deletes on the fly
With SA 4.X - on average 2-6GB and I had to do a quick fix:
59 23 * * * root find /var/lib/amavis/tmp/ -mtime +0 -delete;
