smtp_address_preference (default: any)
The address type ("ipv6", "ipv4" or "any") that the Postfix SMTP client
will try first, when a destination has IPv6 and IPv4 addresses with
equal MX preference. This feature has no effect unless the inet_proto-
cols setting enables both IPv4 and IPv6.
Postfix SMTP client address preference has evolved. With Postfix 2.8
the default is "ipv6"; earlier implementations are hard-coded to prefer
IPv6 over IPv4.
