Topic: Spamassassin Bayes

[kryptos]

Hi All,

based on the wiki:

Setup Blacklists & Bayesian Autolearning
(Much of what follows has been shamelessly copied from the Sonoracomm howto)
The default SME settings (as you can see above) do not include DNSBL filtering, spam rejection, or (which is not obvious from the above) bayesian filtering in spamassassin to allow spamassassin to learn from received email and improve over time.

The following command will enable the default blacklists, enable the bayesian learning filter and set thresholds for the bayesian filter.

config setprop spamassassin UseBayes 1
config setprop spamassassin BayesAutoLearnThresholdSpam 4.00
config setprop spamassassin BayesAutoLearnThresholdNonspam 0.10
sa-learn --sync --dbpath /var/spool/spamd/.spamassassin -u spamd
chown spamd.spamd /var/spool/spamd/.spamassassin/bayes_*
chown spamd.spamd /var/spool/spamd/.spamassassin/bayes.mutex
chmod 640 /var/spool/spamd/.spamassassin/bayes_*
setprop qpsmtpd DNSBL enabled
setprop qpsmtpd RHSBL enabled
config setprop spamassassin status enabled
config setprop spamassassin RejectLevel 12
config setprop spamassassin TagLevel 4
config setprop spamassassin Sensitivity custom

When I arrive with this command i end with an error below:

[root@cdi-postalwise ~]# sa-learn --sync --dbpath /var/spool/spamd/.spamassassin -u spamd
ERROR: configuration specifies 'use_bayes 0', sa-learn disabled

Anybody knows what is the casue for this? Im using SME 7.2

Rocel

BTW: There appears to be an error in the above instructions.

setprop qpsmtpd DNSBL enabled
setprop qpsmtpd RHSBL enabled

Should be

config setprop qpsmtpd DNSBL enabled
config setprop qpsmtpd RHSBL enabled

... and after setting the properties, you must at least do:

signal-event email-update

or (better to be sure)

signal-event post-upgrade
signal-event reboot

Hi all,

What i did was follow this as Ray suggested

http://www.sonoracomm.com/index.php?option=com_content&task=view&id=49&Itemid=32

i have done this before i thought following the other instructions from the wiki might work. I don't have any more problem with enabling Bayesian Autolearning. Thanks!

Using SME Server 7.3 but if you get the above, you need to change the configuration settings in spam assassin to enable bayes.

Code: [Select]

db configuration setprop spamassassin UseBayes 1
signal-event email-update

The wiki page for reference is http://wiki.contribs.org/DB_Variables_Configuration#SpamAssasin

Posted in case it is of use. Took me a while to find it on the wiki but that was probably just me.

Moving this topic to the SME 7.x contribs forum, it is more appropriate there. Thanks!

BTW: There appears to be an error in the above instructions.

setprop qpsmtpd DNSBL enabled
setprop qpsmtpd RHSBL enabled

Should be

config setprop qpsmtpd DNSBL enabled
config setprop qpsmtpd RHSBL enabled

I've corrected the wiki entry; thanks!

Kryptos:
Your original extract from the wiki is missing the last line that says signal-event email-update, which would have activated the changes...
