Hello,
I currently have a setup on my system with what I call "magic folders"
to enable spam filter training. Here's how it works:
1. If you have a false-negative, put the spam into the Spam.Report
folder
2. If you have a false-positive (which has all kinds of ugly
spamassassin protective markup in it), put the message into the
Spam.NotSpam folder
Currently what happens is that a cron job comes along every five
minutes and processes the messages in those folders. In the case of
the NotSpam folder, it strips the message of the spamassassin markup,
retrains the bayesian net, and redelivers the message (e.g. via
deliver). In the case of the Report folder, the message is used to
train the bayesian net (among other things) and then deleted.
I'd love to be able to trigger these actions when the mail is moved,
rather than have a cron job inspecting the mailboxes.
I looked into the antispam plugin
(http://johannes.sipsolutions.net/Projects/dovecot-antispam), which
seems nice but doesn't appear sufficiently generic for my needs. What
would really work is if I could get it set up such that putting a
message into either of those directories is turned into piping the
message to a script of my choosing (a different one for each folder).
Does anyone know a good way of getting my own custom behavior in here,
or is my cronjob setup probably the best way?
~Kyle

Hi The anispam plugin does exactly what you need, and you could forget the cron script. If you use SpamAssassin, you could add a rule to Sieve to move the Spam messages when they arrives to the Spam folder. If a user moves a message from Spam folder to any other folder, then the message is considered a false possitive (when this move is detected you could run sa-learn inmediatly, without the cron script); the other way, when a user moves a message INTO the spam folder you could run again the sa-learn script, but with different parameters. I am testing antispam plugin with dovecot 1.1rcX, but it looks there is a conflict with quota plugin. Anyway you can view the documentation i have done, but it is in spanish. http://wiki.nutum.es/linux/samba/samba_ldap_mds/instalacion_y_configuracion_de_dovecot Regards. 2008/6/11 Kyle Wheeler <kyle-dovecot at memoryhole.net>:> Hello, > > I currently have a setup on my system with what I call "magic folders" to > enable spam filter training.

Basically it will forward the message, as attachment, to spam/notspam addresses that you define. That includes the use of a %u variable expansion, if you choose to use retrain addresses like like spam-username at domain.com or something. I've been pretty happy with with it and it scales a lot better than piping the message into a retrain command, since the mail system itself will handle the load in a more intelligent way.

It works like the regular cron but is driven by filesystem events instead of time events.

You _could_ do that by loading the plugin twice (the plugin supports compiling as a different plugin name) and configuring the first as such: * declare "Spam.NotSpam" as "spam" folder and make the spam->notspam move a no-op, the notspam->spam the reporting and the second * declare "spam.report" as "spam" folder and make the spam->notspam move a no-op, the notspam->spam do the reporting But that's quite complicated. johannes -------------- next part -------------- A non-text attachment was scrubbed...
