Import Postfix 2.8.1. Changes since version 2.7.*:
Postfix stable release 2.8.0 is available. This release continues the
move towards improving code and documentation, and making the system
better prepared for changes in the threat environment.

The postscreen daemon (a zombie blocker in front of Postfix) is now
included with the stable release. postscreen now supports TLS and can
log the rejected sender, recipient and helo information. See the
POSTSCREEN_README file for recommended usage scenarios.

Support for DNS whitelisting (permit_rhswl_client), and for pattern
matching to filter the responses from DNS white/blacklist servers
(e.g., reject_rhsbl_client zen.spamhaus.org=127.0.0.[1..10]).

Improved message tracking across SMTP-based content filters; the
after-filter SMTP server can log the before-filter queue ID (the
XCLIENT protocol was extended).

Read-only support for sqlite databases. See sqlite_table(5) and
SQLITE_README.

Support for 'footers' that are appended to SMTP server "reject"
responses. See "smtpd_reject_footer" in the postconf(5) manpage.
