IMAP Subdirectories in sidebar

[Nathan Huesken <mutt@xxxxxxxxxxxxxxx>]

Hi,

I am using IMAP with subdirectories (for my different mailboxes) and switch 
throught them using the sidebar addon.
I tell imap with the "mailbox" commands about the subdirectories:

mailboxes =INBOX =INBOX/mutt ...

But since I am constantly adding new mail-addresses and removing old ones, I am 
wondering if it is possinle to setup mutt so that it searches for sub 
directories and displayes them in the sidebar without me telling in the 
"mailnoxes" line.
Something like:

mailboxes =INBOX =INBOX/.*

(I hope you get the idea).

I am also wondering if it is possible to create and delete 
Mailboxes/subdirectories in mutt?

Thanks!
Nathan
