It is indeed DEEPLY concerning that IETF emails won=92t be delivered over I=
Pv6.

I must have missed this piece of information before else I would have oppos=
ed it.

Is it an AWS limitation ? AFAIK AWS leads the =91cloud providers=92 on the =
IPv6 front.

Regards but deeply concerned

I get different answers for amazonses.com.
A bunch of 108.138.106.x IPv4, and no IPv6!
But that's not the included SPF list, which is different again, and also no=
 IPv6.
This concerns me if ietf will no longer deliver over IPv6.

    > Are those IP addresses also used by other AWS customers?

Are you concerned that you will be unable to block other AWS customers
without also blocking ietf.org?
