Translate mailbox names to filesystem paths
mbpath [ -C config-file ] [ -q ] [ -s ] [ -m ] [ mailbox-names... ]
Given a mailbox name or a space separated list of mailbox names, mbpath outputs the filesystem path to the mailbox.
Mbpath reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.
-C config-file
Read configuration options from config-file.
-q suppress any error output.
-s if any error occurs, stop processing the list of mailboxes and exit.
-m output the path to the metadata files (if different from the message files).
/etc/imapd.conf
