An on-line version of this announcement is available at http://www.postfix.org/announcements/postfix-2.6.7.html
Postfix legacy release 2.6.7 contains fixes that are also included with Postfix 2.7 (stable release) and Postfix 2.8 (experimental release).
NOTE: Postfix versions 2.3 and earlier are no longer updated.
NOTE: Postfix versions 2.4 and 2.5 are updated only for bugfixes or critical problems.
Bugfix (introduced Postfix 2.6) in the XFORWARD implementation, which sends remote SMTP client attributes through SMTP-based content filters. The Postfix SMTP client did not skip "unknown" SMTP client attributes, causing a syntax error when sending an "unknown" client PORT attribute.
Robustness: skip LDAP queries with non-ASCII search strings, instead of failing with a database lookup error.
Portability: OpenSSL 1.0.0 changes the priority of anonymous cyphers.
Portability: Mac OS 10.6.3 requires <arpa/nameser_compat.h> instead of <nameser8_compat.h>.
Portability: Berkeley DB 5.x is now supported.
