[Dovecot] Multiple mailbox formats, per-user mailbox format support

[Ragnar Rova]

Hello,

I have a setup where each user has different mailbox
formats (some use only /var/spool/mail/user) mailbox format,
some is stored in mbx format ~/INBOX or ~/mbox and
some is stored in maildir format in ~/Mail/

I currently use UW-IMAP to read /var/spool/mail/... and the mbx format
mailboxes in ~/INBOX and mutt to read ~/Mail/... (the maildirs in ~/Mail/
are created by procmail rules)

Does dovecot make it possible to also read the maildir directories i have
in ~/Mail/ without having to reconfigure the delivery/imap system for all
users?

I know I should migrate to use one consistent mailbox format (thinking
about maildir), but to avoid any migration It would be great if dovecot
just would be able to read multiple inboxes in different formats
differently configured on a per-user basis.

I use postfix for delivery/transfer.
