# mbexamine(8)

examine a cyrus-format mailbox

 \*

## NAME

mbexamine - 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*...\

## 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)](/imapd.conf/5.md) file unless specified otherwise by **-C**.  It uses the mboxlist database to locate the mailbox on disk.

## OPTIONS

- **-C** *config-file*

  Read configuration options from *config-file*.

- **-s**

  Dump information for the given sequence number only.

- **-u**

  Dump information for the given uid 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.

## FILES

**/etc/imapd.conf**
