Description
Scripts (based on LearnAsSpam) which allows users to interact with spamassassin rules simply by dropping mail in special folders of their mailbox (working only with imap).
- Learn mail as spam
- Learn mail as ham
- Whitelist the sender so his mails won't be tagged as spam again
Installation
yum --enablerepo=smecontribs install smeserver-learn
enable Bayes. See Bayesian Autolearning as described in the Email page for a full setup. The barely to do would be:
db configuration setprop spamassassin UseBayes 1 config setprop spamassassin BayesAutoLearnThresholdSpam 6.00 config setprop spamassassin BayesAutoLearnThresholdNonspam 0.10 expand-template /etc/mail/spamassassin/local.cf 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_* config setprop spamassassin status enabled config setprop spamassassin RejectLevel 12 config setprop spamassassin TagLevel 4 config setprop spamassassin Sensitivity custom signal-event email-update
Don't forget to configure db key according to your needs and expand config file to activate the contrib.

E.g.:
config setprop LearnAsSpam status enabled config setprop LearnInWL status enabled
Individual configuration is also possible for users with the SpamLinks property
db accounts setprop MYUSER SpamLinks junks,junker
One config file is modified : /etc/cron.d/Learn who need to be expand if prop Learn>cron is modified with the following.
signal-event email-update
also the following should be sufficient:
expand-template /etc/cron.d/Learn
Setup Bayesian Autolearning
You'll also have to setup Bayesian Autolearning as described in the Email page.
Automatic creation of folders
this is not necessary anymore, if you keep the Uniq property enabled. For reference, the script previously here is kept in discussion.
Example of configuration
I like to have my learning folder as subdir of junkmail folder. My thunderbird clients are set to use junkmail folder to put what they find to be a SPAM, but my iOS client wants to use Junk and I do not want to check myself multiple folders. My SME is set to to delete the content of junkmail after 30 days (config getprop spamassassin MessageRetentionTime), but I want that the content of junkmail folder is used to learn before deletion (15 days) leaving me time to find false positives to move them to jumkmail.not_a_spam or moving them myself to jumkmail.junkmail.learn. I keep Uniq enabled to have the IMAP folder created automatically even if users deleted them again and again. I do not want that junkmails that never were downloaded by any client be used to learn, so I keep LearnNew as disabled.
config setprop LearnAsSpam status enabled DeleteAfterLearn enabled DelayToMove 15 SpamLinks Junk dir jumkmail.junkmail.learn Uniq enabled
I want to be able to remove badly SPAM tag when moved to jumkmail.not_a_spam and have them back in my inbox without any new tag.
config setprop LearnAsHam status enabled dir jumkmail.not_a_spam tag "" RemoveSPAMTag enabled Uniq enabled
Finally, I want my SME to learn every hours
config setprop Learn cron hourly signal-event email-update
Uninstall
Simply do :
yum remove smeserver-learn
