[dovecot] INBOX at /var in maildir storage format

Hi

I'm trying to figure out how to set default_mail_env to support such config:

INBOX is in '/var/mail/%u/' (note last slash at the end, %u is an folder with new/tmp/cur subdirs - standard maildir structure).

Other imap folders are stored as files (in mbox format) in direcotry '%h/Mail/'.

Please advise.
