Sieve redirect add resent MTA option

Sieve filter interpretation MTA options:  (0 or 1)
New in  6.3P1. The  MTA option sets the MTA system default for whether  Sieve " " actions  cause addition of Resent-&#x2a; header lines. The default for this option is 1, meaning to add Resent-Date:, Resent-To:, and Resent-From: header lines when performing a " ". This MTA system default may be overridden on a per-action basis using the " " and " " arguments to " ". That is, setting  causes these fields to be generated unless " " is used; whereas setting   causes the fields to be generated only if " " is used.
