I believe the tool you're looking for is 'mbtool' From the man
page:<br>
<blockquote>
<pre>DESCRIPTION
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.

<br>
I just noticed the dates of some old emails are wrongly displayed
on roundcube webmail.
<br>
<br>
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
<br>
<br>
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.
<br>
<br>
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.
<br>
<br>
Thanks.
