MailScanner + Spamassassin 3.13 autolearn not working !

Hello Friends !

I have been running SA for years with mailscanner and some virus  
scanning software on our
mail linux fedora server. This server now runs FC5 and I found out  
some two weeks ago
that bayes database was somehow corrupted so I did go for
fresh mysql bayes database and learned some thousands of saved ham and  
spam messages.
Everything seems to be on order now and I see bayes hits on maillog
as usual.

The problems seems to be that SA never does autolearn even the spam  
value is very high (
like 15 or so ). So the bayes data stays permanent if I do not
train some messages manually by sa-learn.

I have tested also the system so that I used the normal bayes DB on  
/var/spool/spamassassin instead of mysql with same bayes data ! Same  
behavior !

I never see on the maillog the autolearn=spam ham or disabled. No  
autolearn markings at all ! The Autolearn
module is loaded and everything else seems to be running ok. The same  
happens with
autowhitelist. No entries are made to auto-whitelist ! That seems  
strange. The autowhitelist file itself is at /var/spool/spamassassin  
but its allways same size and does not grow !

Im running spamassassin 3.1.3

and here are some lines from spam.assassin.prefs.conf that mailscanner  
uses with SA.

# If your root filesystem is filling up because SpamAssassin is putting
# large databases in /.spamassassin or /root/.spamassassin, you can move
# them using the following lines to point to their new locations.
# The last part of the path is not a directory name, but actually the
# start of the filenames. So with the settings below, the Bayes files will
# be created as /var/spool/spamassassin/bayes_msgcount, etc.

The spamassassin -D --lint works without any problems and all required  
modules are loaded !

Are there some undocumented changes in autolearn behavior with mailscanner ?

here is sa-learn --dump magic output
0.000          0          3          0  non-token data: bayes db version

So I just do not understand what is going wrong there as the SA with  
mailscanner system
has been workin for years and autolearn etc. has been working
nicely too !
