Dkim preserve domains MTA option

DKIM MTA options:  (list of domain names)
(New in Messaging Server 7.0.5.) The   MTA option modifies the effect  of the   and      channel options. When such a channel option is being applied, after first checking each domain on a DKIM-Signature:  header line against     for domain names to ignore,  next the MTA will check the list of domain names specified by    and if a match is found,    mode will  be triggered (further general message processing is terminated). Note that once such a match on the    list is found, the  MTA need not, and does not, bother to scan further in the message or  list for additional matches.
