邮件服务器 Sendmail 8.14.7 发布

Sendmail是Linux/UNIX下的老牌邮件服务器。Sendmail作为一种免费的邮件服务器软件，已被广泛的应用于各种服务器中，它在稳定性、可移植性、及确保没有bug等方面具有一定的特色，且可以在网络中搜索到大量的使用资料。

2013-04-21发布8.14.7,上个版本还是2012-12-24的8.14.6。在三大MTA里，Sendmail和Qmail似乎很少更新了。而Postfix基本是主流了。不过也有Exim,Courier等解决方案。

发布声明及改进：

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.
