I have my postfix/dovecot virtual mail system essentially (otherwise) configured where Postfix is calling Dovecot for its virtual transport:
virtual_transport = lmtp:unix:private/dovecot-lmtp

But I can't for the life of me see how to change the file permissions dovecot uses to create maildir folders and files.  I looked at the maildir, lmtp, and other documents and they are either silent on permissions or seem to reference a shared mail permissions document that claims file and folder permissions are inherited.  I want all files dovecot creates to be made accessible to the mail group.  Please tell me this wasn't hard-coded a la postfix.

Thanks,
