postfix-3.4.6

[Douglas R. Reno]

New point version

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.
