Update to sendmail 8.14.7:  this is a bug fix release.

8.14.7/8.14.7	2013/04/21
	Drop support for IPv4-mapped IPv6 addresses to prevent the MTA
		from using a mapped address over a legitimate IPv6 address
		and to enforce the proper semantics over the IPv6
		connection.  Problem noted by Ulrich Sporlein.
	Fix a regression introduced in 8.14.6: the wrong list of
		macros was sent to a milter in the EHLO stage.
		Problem found by Fabrice Bellet, reported via RedHat
		(Jaroslav Skarvada).
	Fix handling of ORCPT parameter for DSNs: xtext decoding
		was not performed and a wrong syntax check was applied
		to the "addr-type" field.  Problem noted by Dan Lukes
		of Obludarium.
	Fix handling of NUL characters in the MIME conversion functions
		so that message bodies containing them will be sent
		on properly. Note: this usually also affects mails
		that are not converted as those functions are used
		for other purposes too.  Problem noted by Elchonon
		Edelson of Lockheed Martin.
	Do not perform "duplicate" elimination of recipients if they
		resolve to the error mailer using a temporary failure
		(4xy) via ruleset 0.  Problem noted by Akira Takahashi
		of IIJ.
	CONTRIB: Updated version of etrn.pl script from John Beck
		of Oracle.
	Portability:
		Unlike gcc, clang doesn't apply full prototypes to K&R
		definitions.
