[Spambayes] IMAP Filter

Well, according to the RFC, if I append and specify a date, then it
should use that date.  It will be stuffed up at the moment, but I hope
that if I extract the original date from the message (which shouldn't be
difficult) and append with that date, things should be ok.  A nice
theory, anyway :)

Heh.  Now we can be just like Outlook ;)  Seriously, I suspect Outlook
will have to take the same path here and note the unread status of the
message before doing anything to it, and setting it to that status once
it's done.  (I'll add this to the IMAP filter soonish).

Not at the moment.  All the messages are tracked by UID, but folders
aren't at the moment.  It would be much nicer to have UIDs for these
(from the UIDVALIDITY response), except that there's still the problem
of identifying them the first time.  (Unless I create some sort of GUI
like the pop3proxy web ui).

See previous message re: flags.  One advantage of re-writing is that we
get to add the spambayes headers.  It would be nicer to be able to
move/update messages, but never mind.

Thanks for the comments, much appreciated.
