Update Postfix to version 2.8.13. Changes since version 2.8.12:
- The postscreen_access_list feature failed to ignore case in the first
character of a command (e.g., permit, reject, etc.). Reported by
Francis Picabia. (This fix is incorrectly listed in the HISTORY
files of earlier releases, and will be removed with a future patch.)
- Strip the datalink suffix (e.g., %eth0) from IPv6 addresses returned
by the system getaddrinfo() routine. Such suffixes break the default
mynetworks value, the Postfix SMTP server's reverse/forward DNS
name/address mapping check, and possibly more.
- To eliminate the possibility of collisions with connection cache
lookup keys, the Postfix LDAP client now computes those lookup keys
by joining the number-valued connection properties with ASCII null,
just like it already did with the string-valued connection
properties.
- There was a memory leak during one-time TLS library initialization
(introduced with Postfix 2.5). Reported by Coverity.
- There was a memory leak in the unused oqmgr(8) program (introduced
with Postfix 2.3). Reported by Coverity.
