Q about mailboxes saved config

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
Still on my filter patch (and still waiting for feedback), I wanted to know
which mailboxes get saved in config files ? Because on the 1.1.7 I'm
working on, a local mailbox which is not a special one (ie inbox,trash ...)
doesn't have his config. saved or loaded. That's a problem for me because I
want to save for each mailbox a list of filters associated to it.
Thanks
Bye
Manu
