Yes it is a bug, in my opinion. Location should allow any where within
the mail home dir.

Based on the doc here we should be able to use mixed storage types
mbox maildir etc

http://wiki.dovecot.org/Namespaces

if location is set to following, we get error prompt via client too.

location = maildir:~/mdbox/expunged


I have mail_location dynamically set in the database....we only
convert few user to mdbox to start with. So mixed storage would be
nice.

Forgot to mention.

If we select prefix. .EXPUNGE imap generate a core dump.
