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.
−C config−file
Use the specified configuration file config−file rather than the default imapd.conf(5).
−u uid, −−uid=uid
Dump information for the given uid only.
−s seqnum, −−seq=seqnum
Dump information for the given sequence number only.
−q, −−check−quota
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, −−check−message−files
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.
