-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Just to let you know, on the offlineimap there is also a discussion going on about gmail labels / folders / sync and it looks as if something is happening on that side: http://article.gmane.org/gmane.mail.imap.offlineimap.general/5915 Would be nice, if this could work together nicely with notmuch.
