The smeserver-learn package stores all key values needed in the configuration db. The right angle character, >, indicates that is a prop and not a key. For example, "status" is a property and "enabled, disabled" presents the allowed input values.

One config file is modified : /etc/crontab who need to be expand if prop Learn>cron is modified.
+
E.g.:
 +
  config setprop LearnAsSpam status enabled
 +
  config setprop LearnInWL status enabled
   −
=== Uninstall ===
+
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 [[Email#Bayesian_Autolearning | 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  the content of junkmail folder to be used to learn before deletion (15 days) leaving me time to find false positives to move them to junkmail.not_a_spam or moving them myself to junkmail.junkmail.learn. I keep Uniq enabled to have the IMAP folder created automatically even if users delete them again and again. I do not want 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 junkmail.junkmail_learn Uniq enabled
 +
 
 +
I want to be able to remove badly placed SPAM tag when moved to junkmail.not_a_spam and have them back in my inbox without any new tag.
 +
config setprop LearnAsHam status enabled dir junkmail.not_a_spam tag "" RemoveSPAMTag enabled Uniq enabled
 +
 
 +
Finally, I want my SME to learn every hour.
 +
config setprop Learn cron hourly
 +
signal-event email-update
 +
 
 +
===Uninstall===
