The first new parameter is called inet_protocols. This specifies what
protocols Postfix will use when it makes or accepts network connections,
and also controls what DNS lookups Postfix will use when it makes
network connections.
/etc/postfix/main.cf:
# You must stop/start Postfix after changing this parameter.
inet_protocols = ipv4 (DEFAULT: enable IPv4 only)
inet_protocols = all (enable IPv4, and IPv6 if supported)
inet_protocols = ipv4, ipv6 (enable both IPv4 and IPv6)
inet_protocols = ipv6 (enable IPv6 only)
By default, Postfix uses IPv4 only, because most systems aren't attached
to an IPv6 network.
