Postfix version 2.2 IPv6 support is based on the Postfix/IPv6 patch
by Dean Strik and others, but differs in a few minor ways.
-
main.cf: The
inet_interfaces parameter does not support
the notation "ipv6:all" or "ipv4:all". Use the
inet_protocols parameter instead.
-
main.cf: Specify "
inet_protocols = all" or
"
inet_protocols = ipv4, ipv6" in order to enable both IPv4
and IPv6 support.
-
main.cf: The
inet_protocols parameter also controls
what DNS lookups Postfix will attempt to make when delivering or
receiving mail.
-
main.cf: Specify "
inet_interfaces = loopback-only"
to listen on loopback network interfaces only.
-
The
lmtp_bind_address and
lmtp_bind_address6
features were omitted. The Postfix LMTP client will be absorbed
into the SMTP client, so there is no reason to keep adding features
to the LMTP client.
-
The SMTP server now requires that IPv6 addresses in SMTP
commands are specified as [ipv6:ipv6address], as
described in
RFC 2821.
-
The IPv6 network address matching code was rewritten from
the ground up, and is expected to be closer to the specification.
The result may be incompatible with the Postfix/IPv6 patch.
