MBEXAMINE(8)

NAME
mbexamine - Cyrus IMAP documentation

Examine a cyrus-format mailbox

SYNOPSIS

mbexamine [ -C config-file ] [ -u uid ] mailbox...
mbexamine [ -C config-file ] [ -s seqnum] mailbox...
mbexamine [ -C config-file ] -q mailbox...
mbexamine [ -C config-file ] -c mailbox...

DESCRIPTION

mbexamine will examine the header, index, and cache files of a cyrus format mailbox and dump the information contained therein. It can also limit its output to a specific uid or sequence number, through use of the -s and -u switches.

mbexamine reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C. It uses <configdirectory>/mailboxes.db to locate the mailbox on disk.

OPTIONS

-C config-file
    Use the specified configuration file config-file rather than the default imapd.conf(5).

-u uid
    Dump information for the given uid only.

-s seqnum
    Dump information for the given sequence number only.

-q  Compare the quota usage in cyrus.index to the actual message file sizes and report any differences. If there are differences, the mailbox SHOULD be reconstructed.

-c  Compare the records in cyrus.index to the actual message files report any differences. This can help detect issues if messages files were manipulated manually and/or restored incorrectly.

EXAMPLES

mbexamine user.jsmith
Examine the mailbox hierarchy rooted at user.jsmith.

mbexamine -u 00000004 user.jsmith
Examine the mailbox hierarchy rooted at user.jsmith looking for messages with UID = 00000004.

mbexamine -q user.jsmith
Examine the mailbox hierarchy rooted at user.jsmith checking quotas.

mbexamine -c user.jsmith
Examine the mailbox hierarchy rooted at user.jsmith comparing index records to the actual message files in the mailbox directory.

FILES

/etc/imapd.conf, <configdirectory>/mailboxes.db
