mbtool [ -C config-file ] -r mailbox... mbtool [ -C config-file ] -t mailbox...
mbtool is a tool for performing various actions on the indexes of a
list of mailboxes. The only actions currently supported are -t,
which will normalize the
internaldate time stamp of each record in
the index to GMT, and -r which will create a new unique ID for each
Only one action may be given and at least mailbox must be listed.
It is intended that mbtool will be extended over time to perform more such actions.
mbtool reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.
Use the specified configuration file config-file rather than the default imapd.conf(5).
internaldateon all index records of all listed mailboxes to match the Date: header if they're off by more than a day, which can be used to fix up a mailbox which has been restored from backup and lost its internaldate information.
Create a new unique ID for all listed mailboxes.
