/REPAIR
       /NOREPAIR [=BEFORE=time | =SINCE=time]

    Optional. Default: /NOREPAIR.

    Corrects errors as follows:

    o  Resubmits for delivery each valid control file in the SMTP
       directory with no entry in an SMTP queue.

    o  Deletes each invalid control file (fails the internal
       consistency check) and the corresponding queue entry.

    o  Either requeues or deletes messages placed on hold.

    Supports the following options:

    o  =BEFORE=time

       -  Deletes files created before the specified time.

       -  Default: Current date and time.

    o  =SINCE=time

       -  Deletes files created since the specified time.

       -  Default: Deletes all files.

    Do not use /REPAIR with /DELETE if their time frames conflict.
