mhbuild will honor MIME directives by default. And added support
for special #on/#off/#pop directives to control the MIME directive
processing state.
+- Added -messageid switch to send(1) and post(8). This allows
+ selection of the style to use for generated Message-ID and
+ Content-ID header fields. The default localname style is
+ pid.time@localname, where time is in seconds, and matches previous
+ behavior. The random style replaces the localname with some
+ (pseudo)random bytes and uses microsecond-resolution time.
