Re: Bayes auto-learn - Solved
Restored my last copy of my manually learned bayes database from the "bad"
directory to the new location. Let it cook for a day. Of the messages that
made it through postscreen, RBLs, etc since my logs rotated early this
morning, 93% were autolearn=no, 2% autolearn=spam, 5% autolearn=ham. ZERO
autolearn=unavailable.
This is solved.
Summary for posterity for anyone who may run into the same problem. Some
tags for searching:
Centos7 (selinux disabled at the time of testing)
Postfix 3.2.2
Amavisd-new amavisd amavis 2.11.0
Spamassassin 3.4.0
bayes
autolearn=unavailable
I strongly suspected bayes auto-learn was not functioning. Read the thread
for evidence. In local.cf had the bayes path set to:
/etc/mail/bayes/bayes
Don't remember if it came packaged that way or if I followed someone else's
"guide" to ed up with that bad location. I do see one well written guide
that specified that folder, honestly I'm not sure. No matter.
In any case, the end result was that any message that would have been
autolearned got "autolearn=unavailable" and did not learn.
The fix for this setup as listed above was to NOT have the directory under
/etc. Even with wide open (777) write permissions, amavisd/SA was
apparently unable to write there.
I moved the bayes database under /var/spool/amavisd/bayes and all now
functions properly. Note the default if no path is specified is
/var/spool/amavisd/.spamassassin/bayes IIRC (assuming /var/spool/amavisd is
the home directory for amavis) I tested both, it appears happy with either.
local.cf:
bayes_path /var/spool/amavisd/bayes/bayes
I now have a journal file FWIW:
[root@mail2 root]# ls -la /var/spool/amavisd/bayes
total 4280
drwx------ 2 amavis amavis 4096 Aug 11 16:07 .
drwxr-xr-x 7 amavis amavis 4096 Aug 10 22:18 ..
-rw-rw-rw- 1 amavis amavis 81888 Aug 11 16:07 bayes_journal
-rw-rw-rw- 1 amavis amavis 86016 Aug 11 16:07 bayes_seen
-rw-rw-rw- 1 amavis amavis 5267456 Aug 11 16:07 bayes_toks
And my database is happy:
[root@mail2 root]# su amavis -c 'sa-learn --dump magic'
0.000 0 3 0 non-token data: bayes db version
0.000 0 359 0 non-token data: nspam
0.000 0 494 0 non-token data: nham
0.000 0 149970 0 non-token data: ntokens
I now know way more about amavis-new and spamassassin than I did when I
started. Guess that's the silver lining to a few days of hair pulling.
Thanks,
Scott

You do need the epel-release package installed to use this.

I suppose I could publish the Centos 7 x86/64 RPMs I build and use on my
website. They wouldn't be signed...

I'm chicken. :D
I don't have much (almost no) experience overriding those yum packages. And
those warnings I got when I rebuilt from source made me nervous.
Maybe when the dust settles...
