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.
