Hi!
I have considered methods to let SPAMs which went under the spamassassin radar (i.e. passed spamassassins check) but failed the member of list check (which has so far been a 100% filter for this category) to be somehow sent into the spamassassin learning process, so that list-admins/moderators can teach the spamassassin filter. When doing this on a larger site like the one which my mailman installation sits on also means that I don't have direct access to the spamassassin processing, so some form of passing may be necessary.
I've toyed with these alternatives:
The moderator gets the option of click a "Is SPAM" check-box for a caught message. A site-configuration decides weither this means forwarding the spam to an email address, tossing it on an MBOX file or saving it as a separate file.
The moderator gets a different default forward email address to a hidden list (learnspam@domain), this hidden list archives the emails as normal but has normally no members.
Have the front-end of the first proposal but actually use the normal email listing mechanism of the second proposal.
The later of these are really just a quick-and-dirty implementation of the first, but it does have its merits.
Any thoughts?
Cheers, Magnus
