Hi Horacio,

nice work. Working directly with GMail labels is probably a good idea
(the other option is to move messages between IMAP folders). I have a
design question though:

Should remote sources be part of regular sup? Or should rather the
fetching and syncing be put in a separate script which creates a LevelDB
setup like you have it with a Gmail source in sup working directly on it?

Recall that the IMAP source was removed in 52e29ba [1] (discussion
probably on the mailinglist somewhere).

I like this approach for GMail, but I would like to see it for regular
IMAP sources as well with folders as labels.. I briefly experimented
with a maildir-root folder approach [2] which treats all underlying
maildirs as sources which correspond to a label (do not use,
incomplete). It of course presents a plethora of questions on how to
sync messages between labels, but implementing it is is probably
relatively straight forward.

This normally runs in a separate thread, I don't think maildir really
stops the polling - so I sometimes get an error if I quit sup while the
polling is running and various stuff just disappears underneath the poller.

I don't have the chance to get into your other questions at the moment.
