I have tried again, unsuccessfully, to get Mail operating smoothly in IMAP.
This time (I seem to have a different problem each time I try!) I have unread messages in the inbox, as indicated in brackets in the list of mailboxes but when I open the inbox, it is empty. I have set the IMAP path prefix to "inbox".
The other mailboxes are functioning correctly.
The "Help" function doesn't.
Any suggestions?
