Spamassassin Autolearn

kwebdesign · Unread post by **kwebdesign** » Sun May 25, 2008 8:07 am

I see in my mail log that spamassassin claims to be autolearning messages (as expected), but when I look at the stats (sa-learn --dump magic), I don't see the number of ham and spam messages increasing. Should it be? Does spamassassin keep its autolearn data somewhere besides the bayes db?

youve got to set the path to the bayes db of the user it runs as. If its qmail-scanner its in /var/spool/qscan/.spamassassin

The bayes db is there, and it gets updated when I use sa-learn manually, it's just not updating via autolearn. Do I have to specifically set that up? If so, where?

Thanks.

Nope, its all automatic

So, are you saying the stats should be increasing as it autolearns? Because mine is not doing that.

Yes, I suspect its because you're not looking at the right files

Here's what I'm doing:

# sa-learn --dump magic /var/spool/qscan/.spamassassin
0.000 0 3 0 non-token data: bayes db version
0.000 0 212 0 non-token data: nspam
0.000 0 1899 0 non-token data: nham
0.000 0 82770 0 non-token data: ntokens
0.000 0 963261639 0 non-token data: oldest atime
0.000 0 1211878301 0 non-token data: newest atime
0.000 0 0 0 non-token data: last journal sync atime
0.000 0 0 0 non-token data: last expiry atime
0.000 0 0 0 non-token data: last expire atime delta
0.000 0 0 0 non-token data: last expire reduction count

When I run sa-learn against a handful of spam messages, the second line (212 messages) increases. However, it's not increasing as SA autolearns.

You might want to double check the user it is running as

try:

Code: Select all

sa-learn --dump magic --dbpath /var/spool/qscan/.spamassassin

Aha - thanks exi1ed0ne. That revealed something entirely different:

# sa-learn --dump magic --dbpath /var/spool/qscan/.spamassassin
0.000 0 3 0 non-token data: bayes db version
0.000 0 1290838 0 non-token data: nspam
0.000 0 97177 0 non-token data: nham
0.000 0 177340 0 non-token data: ntokens
0.000 0 1211560886 0 non-token data: oldest atime
0.000 0 1211921102 0 non-token data: newest atime
0.000 0 1211921112 0 non-token data: last journal sync atime
0.000 0 1211906518 0 non-token data: last expiry atime
0.000 0 345600 0 non-token data: last expire atime delta
0.000 0 36598 0 non-token data: last expire reduction count

So, it appears that when I run sa-learn manually, it is putting the data in /root/.spamassassin/ instead of /var/spool/qscan/.spamassassin/. Looking at the man pages, it appears that I can specify the db directory when running sa-learn, and that should put the data in the right place.

Scott - after re-reading your previous answers, I realize that's what you were trying to tell me. Sorry - I just mis-understood. Thanks for your help as always!
