I've been trying to get nnmaildir to work along with mbsync (which syncs IMAP and Maildir mailboxes) and I just cannot get it to work with gnus.
With the following select method:
(nnmaildir "calgary" (directory "~/mail/ucalgary"))
I can open the connection and the server browse buffer shows all the groups:
K 0: Calendar U 0: Inbox K 0: Sent Items
When I open the Inbox I get the following error:
gnus-select-newsgroup: Couldn't request group nnmaildir+calgary:Inbox: No such group: Inbox
Now if I look in
/home/crb/mail/ucalgary/Inbox/cur/ there are a number of read and unread messages for example
Any advice on how to fix this?
