Hello,
I found the following patch:
http://da.andaka.org/Doku/imapspamfilter.html
To describe it briefly, it automatically trains the SPAM filter when the
user moves messages to a SPAM or HAM folder.
First, what do you think about this in principal?
I see two design issues:
1. The user does not have the chance to use his own preferred settings,
as everything is controlled by an environment variable.
2. The server freezes until the SPAM learner has done its job.
I liked that patch when I first saw it. Thinking twice, I found no way to
turn it into a sound generically useful improvement that Sam can accept.
Training a filter is an interactive job. Blindly moving messages will
always lack feedback or context sensitive help. Users will have a hard
time trying to match that with their client's spam filter settings.
In addition, it will be incompatible with webmail. In my case, the latter
is primarily needed during off-site work or vacations, which is exactly
when light travelers mostly miss their client's spam filters. Hence, I
realized it's not much of an option for me.
Personally, I would solve it by specifying a new column (or more than
one) in the user database which includes the SPAM policy. The learning
would be done in the background without the server waiting for the
process to finish.
And how do users set their own policy?
I am ready to do the coding, but as I am quite new to Courier, I would
like to hear about your opinion.
I don't think the spam filtering task suits an imap server. I'd rather
link it to the webmail server, because of those interactivity requirements.
That's what I meant in

Webmail might delegate some controls, e.g. an added "Junk" button at the
bottom of folder views, or an added image button in the toolbars of message
views, to some dynamically loaded software that implements site-specific
functionalities. Adding a custom section in the "Preferences" page might
become a quite popular option.
QUICA may provide an alternative framework for developing similar tasks. See
