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) <#std-cyrusman-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) <#std-cyrusman-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.
