Nice :)

Here's what my offlineimap gets going through a skanky little proxy
that I coded up in Perl to interfere with the stream and enable

COMPRESSION RATIO: [8 fromfm] 27932/172698 = 16.2%
COMPRESSION RATIO: [10 fromfm] 428077/2904757 = 14.7%

On the two accounts that I'm using.

That's a pretty nice FLAGS compression :)

Bron ( ok, ok - so if it used CONDSTORE it would probably save
       50 times that, but I haven't got around to hacking
       CONDSTORE into offlineimap yet )
