Spamassassin Autolearn not working ?

[Joni Bäcklund <jo...@connect.fi>]

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 so that I used the normal bayes DB on  
/var/spool/spamassassin

I never see on the log the autolearn=spam ham or disabled. 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 strage.

Im running spamassassin 3.1.3
perl-5.8.8
mailscanner-4.55.7-1

and here is the  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.

auto_whitelist_path        /var/spool/spamassassin/auto-whitelist
auto_whitelist_file_mode   0600
use_auto_whitelist      1
#bayes_path                 /var/spool/spamassassin/bayes

bayes_sql_password      XXXXX
bayes_sql_override_username XXXX


# Most people don't use NFS-shared Bayes databases
# so this is added for SpamAssassin 3
lock_method flock
required_hits 4.5
bayes_auto_learn_threshold_spam 8.0
bayes_auto_learn 1

# Most people don't use NFS-shared Bayes databases

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

Are there some undocumented changes in autolearn behavior:

here is sa-learn --dump magic output
0.000          0          3          0  non-token data: bayes db version
0.000          0       5486          0  non-token data: nspam
0.000          0       7142          0  non-token data: nham
0.000          0     187972          0  non-token data: ntokens
0.000          0 1036499585          0  non-token data: oldest atime
0.000          0 1151841259          0  non-token data: newest atime
0.000          0          0          0  non-token data: last journal  
sync atime
0.000          0 1151833489          0  non-token data: last expiry atime
0.000          0   22118400          0  non-token data: last expire  
atime delta
0.000          0      16694          0  non-token data: last expire  
reduction count


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
