You're probably right.  sb_imapfilter does run through all messages in your
'watch' folders.  (More specifically, it does a search for all undeleted
messages, then gets just the headers (no body) for all of those.  It then
compares the MessageID header to the message database, and classifies
(including getting the full message) only those which haven't been seen
already.

This could probably be changed to just do a search for the MessageID (or
X-Spambayes-ID) header, which would speed it up a little.  Patches are
welcome :)
