Re: [sup-devel] A maildir root source: syncing labels with maildirs (imap folders)

[Steven Schmeiser <steven@schmeiser.org>]

Hi,
I'm very interested in trying out this branch.

I don't know the sup internals very well, so I'm having a hard time figuring this out on my own, but what config options need to be changed/set to use maildir-root?  I'm currently using marildir-sync.

Thanks for all your work on sup!

Steve
