For years the trailing slash has indicated the mailbox format as maildir, and dovecot has been happily autodetecting these maildirs without a problem.

In our case in addition to dovecot we have a combination of postfix and a legacy courier-imap, how will these the be affected by the addition of "maildir:"?

What I don't understand is why autocreate is ignoring the long standing convention that the trailing slash indicates maildir, and whether this is intentional or whether there is some reason for it.
