What does this have to do with my sending domain? v6 is configured on my sending domain but that shouldn't matter anyway. James is initiating a connection to the recipient. The DNS on my domain doesn't even matter as james is doing a DNS lookup for the recipient domain, not mine, and is picking the A response instead of a AAAA even when one is available. When I receive email from gmail or other v6 capable senders James receives on v6. When I send email my connection to james is v6. The only time v4 is used when v6 is available is on outbound mail from james to the recipient's server. Usually java apps prefer v4 over v6 for DNS lookups unless you specify -Djava.net.preferIPv6Addresses=true however james seems to ignore that.
