I don't see the need for a local database.

Mark as Junk will pipe the entire mail into 'sa-learn --spam'. Now, a
custom sa-learn script just could pick up this mail and send it to a
centralized server -- the one running the "spam fighting tool" on it.
One possible solution for this "sending" is actually sending by mail to
a dedicated "user", attaching the mail to be learned. The originl user
account is known, so a script on the recipients ond can do the magic.

Uhm, ever thought about sending a mail? This does not involve logging
in.
