Ever? Even if it became common practice? I guess that the standards process
isn't going to lead on this question.
The idea of not accepting mail from domains with only AAAA records
might be worth pursuing. I agree that despite what 5321 says, it seems
pretty unlikely that such domains would ever send mail anyone wanted
to receive.
Yes. Hey, I'm not even sure that we'd accept that email right now. I simply
don't know if my MTA is IPv6 compatible in that way. I guess that I'd
better find out...
Right, it seems that the MTA is capable, if compiled with IPv6 support, but
since we've not got any IPv6 routing to the world on our network, our
sender domain verification tests simply aren't going to work. That's nice.
I've never had any complaints, and I will ensure when we do deploy IPv6, I
don't permit email from domains that have AAAA but not A or MX records.
