Postfix stable release 3.4.6 and legacy releases 3.3.5, 3.2.10, 3.1.13

[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.4.6.html]

Fixed for all supported stable releases:

* Workaround for implementations that hang Postfix while shutting
down a TLS session, until Postfix times out. With
"tls_fast_shutdown_enable = yes" (the default), Postfix no
longer waits for the TLS peer to respond to a TLS 'close'
request. This is recommended with TLSv1.0 and later.

* Fixed a too-strict censoring filter that broke multiline Milter
responses for header/body events. Problem report by Andreas
Thienemann.

* The code to reset Postfix SMTP server command counts was not
called after a HaProxy handshake failure, causing stale numbers
to be reported. Problem report by Joseph Ward.

Fixed for Postfix 3.3 and 3.4:

* "smtp_mx_address_limit = 0" no longer meant 'unlimited'. Problem
report by Luc Pardon.

Fixed for Postfix 3.4:

* postconf(5) documentation: tlsext_padding is not a tls_ssl_options
feature.

* smtp(8) documentation: updated the BUGS section text about
Postfix support to reuse open TLS connections.

* Portability: added "#undef sun" to util/unix_dgram_connect.c.
