cyrus and ifile - a good fit?

[John Hughes]

Like many people I'm being buried under the incoming tide of SPAM.

I've got various measures in place (heuristics in sieve; some of the
less absolutist DNS blackholes in my sendmail config).

They are by no means 100% successful.

I'm toying with the idea of some kind of learning filtering system.

It looks to me like ifile http://www.nongnu.org/ifile/ could be a
pretty good fit with Cyrus imap.  It could learn what is spam simply
by where I file a message.

This could be done by putting calls to ifile into the code where
messages are filed into folders.

A sieve extension would be used to file into the most appropriate folder,
based on the ifile database.

Anyone else looked at this?
