Restore message date from "Date:" field

[Nic Bernstein]

Gionatan,
I believe the tool you're looking for is 'mbtool'  From the man page:

    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.
    ...
    EXAMPLES*mbtool -t*  user.jsmith

        Normalize |internaldate| on all index records in /user.jsmith/.

    Working  on  user.jsmith...
