Well, here's a development... About the only difference in my old, functioning box and this new "clean" install was the location of the bayes files. Old box: /var/spool/amavisd/.spamassassin/ New box: /etc/mail/bayes The other details that caught my attention were that on the old box, the ONLY bayes thing that was explicitly set was the path, which was: bayes_path /home/amavis/.spamassassin/bayes On this (new) box, I commented out most of the bayes settings similarly. Restarted amavis/SA and got some errors about no bayes db. Ignored. Sent an email anyway. Guess what? autolearn=ham right out of the gate, it and created the database files. And the very next message received was also shown as autolearn=ham. ** that eliminates any doubt that a minimum corpus is necessary to autolearn (whether that's a good practice is a different topic). I cleared the db's with sa-learn --clear. I received a new message, autolearn=ham, again. Result: [root@mail2 .spamassassin]# su amavis -c 'sa-learn --dump magic' 0.000 0 3 0 non-token data: bayes db version 0.000 0 0 0 non-token data: nspam 0.000 0 1 0 non-token data: nham [root@mail2 root]# ll /var/spool/amavisd/.spamassassin total 28 -rw-rw-rw- 1 amavis amavis 12288 Aug 10 21:20 bayes_seen -rw-rw-rw- 1 amavis amavis 12288 Aug 10 21:20 bayes_toks -rw-r--r-- 1 amavis amavis 1869 Aug 8 15:32 user_prefs I gradually restored all the bayes settings in local.cf, restarting amavis each time, clearing the db and sending that same test message. Each time the result was autolearn=ham Finally to the path setting: I tried setting the default path, and changing the path filename suffix of bayes to mybayes for curiosity... bayes_path /var/spool/amavisd/.spamassassin/mybayes Upon sending a test message, SA promptly auto-learned as ham and created the 2 new files starting with "mybayes" instead of bayes. So changing the filename didn't hurt autolearn Next I kept the new name and changed the folder back to where it was: /etc/mail/bayes/mybayes Send a test message This time, NO new file was created. It apparently cannot write to it. Permissions on mail, and on bayes are both amavis:amavis & 777. **** autolearn=unavailable **** (As Matus expected) Next, I log on as amavis. cd to /etc/mail/bayes. Create a file, edit it, and then delete it. User amavis CAN write there. I verify I'm amavis, Try to cd to some other user's folder, get "permission denied", check. Finally, because I don't like the hidden directory anyway, I try to move the bayes folder from the default. I configure the bayes path to: bayes_path /var/spool/amavisd/bayes/bayes Send my test message, voila, db files created, and autolearn=ham Success! (tentative, cautiously optimistic) I hope I have solved the mystery. For reasons beyond my skill set, SA will not auto-learn to a bayes db in a folder in /etc/mail/bayes. Regardless of wide open permissions on everything except /etc. And the user's confirmed ability to write to the folder. Bug I guess? SHIT! What a PITA to figure out. I'm gonna let this cook overnight and see how it does. Will report back. -- View this message in context: http://spamassassin.1065346.n5.nabble.com/Bayes-auto-learn-not-happening-tp138065p138268.html Sent from the SpamAssassin - Users mailing list archive at Nabble.com.
