Hello.
With some simple changes to courier IMAP, it's easy to install a
learning system for spam mail. The system relies on the creation of two
simple scripts, which courier will launch when the user moves messages
to two special folders. Those folders are checked for existence after
the user login into courier IMAP, and they are created automaticly if
not present.
The modification to courier IMAP is easy: when the user moves messages
to a folder called "LearnSPAM", a script called "LearnSPAM.sh" (which
must be in a location in the PATH system variable) is launched with the
user name as a parameter. Such script should be created depending on
which anti-spam package is in use, and should perform the necessary
tasks so such subfolder in the user's homedirectory is processed by the
anti-spam package to learn. When the user moves messages to a folder
called "LearnNoSPAM", a script called "LearnNoSPAM.sh" is launched as
well, with the user name as a parameter. Such script should interface
with the anti-spam package as well so it learns that such messages are
not spam.
That way, we avoid the need of having a script which scans every user
LearnSPAM/LearnNoSPAM folders on a timely basis, meaning that we are
only going to scan such folder for a user when it's really needed.
The patch applies to the imapd.c file.
Cheers.
