I believe the tool you're looking for is 'mbtool' From the man page:
http://www.cyrusimap.org/imap/reference/manpages/systemcommands/mbtool.html?highlight=mbtoolDESCRIPTION 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 mailbox. ... -t Normalize internaldate on all index records of all listed mail‐ boxes to match the Date: header if theyâre off by more than a day, which can be used to fix up a mailbox which has been re‐ stored from backup and lost its internaldate information. ... EXAMPLES mbtool -t user.jsmithNormalizeinternaldateon all index records in user.jsmith.Working on user.jsmith... 00000001: Tue, 08 Jul 2014 16:45:18 -0500 => Mon, 07 Jul 2014 20:44:18 +0000 00000002: Tue Jul 08 16:45:13 CDT 2013 => Fri, 30 Aug 2013 19:46:03 +0000 <...>

Hi all,
I just noticed the dates of some old emails are wrongly displayed on roundcube webmail.
In short, the list view shows the filesystem date of the affected messages (ie: mtime of u.1 file), rather than what is found in the "Date:" header field
These were emails migrated from an old system, but I vaguely remember I had some issue at the time which I solved with some combination of rsync+imapsync.
Can "reconstruct" be used to repopulate the index file with the correct date from "Date:" field? If not, what I can do to solve the issue? I already tried "reconstruct -u user@domain -x -f -r -G", but with no avail.
Thanks.
