Topic: setting BayesAutoLearnThreshold

[idyll]

In dialog with Michael Weinberger and his smeserver-spamassassin-features-0.0.2-0.noarch.rpm contrib we briefly discussed setting a threshold differently. He requested I post this in the forum for others to see and share.

Namely, of the  SPAM getting through the multiple processes on my 7.3 server, a significant number of those are in the range 3.5 to 4.0. The SPAMMERS are getting clever.

So I wish to

# config setprop spamassassin BayesAutoLearnThresholdSpam 3.5
# signal-event email-update

The problem is the setting will not stick, it will only stick at a rounded number like 3 OR 4 but not 3.5 or even 3.75.

The Apache WIKI indicates it can be set to x.xx.

So I am missing something. Anyone have any insight on how I might get this setting changed and have it stick?

If this is possible it would thus correctly tag approximately 150-200 SPAM a day for me. It's worth pursuing.

BUG Submitted.

Unless you have to, I dont like adding properties to the config database that dont exist in SME already. And you dont have to.

Your goal is to have SME include your extra settings in /etc/mail/spamassassin/local.cf, because thats what spamassassin reads when it runs.

To see the current local.cf type:

nano /etc/mail/spamassassin/local.cf

SME uses several small template files to generate local.cf. These files are located in /etc/e-smith/templates/etc/mail/spamassassin/local.cf/

To add the settings you want, use nano to create a file in that directory named 15bayes_settings:

nano /etc/e-smith/templates/etc/mail/spamassassin/local.cf/15bayes_settings

In the file add these lines:

bayes_auto_learn 1
bayes_auto_learn_threshold_nonspam 0.1
bayes_auto_learn_threshold_spam 12.0


Save and make sure the permissions on the file match the other files in that directory.

Then you must:

expand-template /etc/mail/spamassassin/local.cf
svc -t /service/spamd

To see changes:

nano /etc/mail/spamassassin/local.cf

and watch these logs for errors:

/var/log/spamd/current
/var/log/qpsmtpd/current
