How do I test my IPv6 capable mailserver?


Just a quick tip: You have Postfix running and want to enable IPv6 for your email as well? After quite some playing around I finally got it right:

inet_interfaces = 127.0.0.1, 94.229.77.82, 2a01:348:6:315::2, ::1
inet_protocols = ipv4, ipv6

This makes Postfix listen only where you actually need it to – I dont like daemons listening on interfaces where they are not serving any requests.
