Examine a cyrus-format mailbox
mbexamine [ -C config-file ] [ -u uid ] mailbox...
mbexamine [ -C config-file ] [ -s seqnum ] mailbox...
mbexamine [ -C config-file ] -q mailbox...
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 the mboxlist database to locate the mailbox on disk.
Read configuration options from config-file.
Dump information for the given sequence number only.
Dump information for the given uid only.
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.
