Re: spam filtering using IMAP ?

[Ted Zlatanov <tzz@lifelogs.com>]

You could actually write a wrapper (let's say for Bogofilter) which
invokes Bogofilter on the server.  Modify spam-bogofilter-path, and
have the wrapper invoke bogofilter on the server over SSH or however
you want.  It will be slow, but it can be done.  Then you can just use
bogofilter as a spam/ham processor in spam.el, and it will update the
database on the server.

You could also, on the server side, periodically connect to IMAP and
process any new messages in the spam/ham folders you define.  That's
completely outside of the Gnus/spam.el domain though - you would only
be using Gnus/spam.el to move messages around.

For incoming mail, use spam-check-bogofilter-headers instead of
spam-check-bogofilter, and set up bogofilter to process your mail on
the IMAP server.  All spam mail (with the "X-Bogosity: Yes" header)
will go to the spam-split-group.
