currently, it is acceptable to use IPv4-only services for sending e-mails.
Whether or not you feel comfortable *receiving* mail over IPv6 is, of course, your choice. This is communicated by having appropriate DNS records. This is no reason whatsoever to limit the sending side to "we will always only do v4, even if the reciever signals willingness to do v6". At least *our* Anti-Spam appliance has learned to do IPv6 reputation over 10 years ago, and this just works. We have no idea how they do it, and we do not really want to know - we asked them "make it happen or we will have to buy something else" and they did. The time for presenting excuses why deploying IPv6 is hard / impossible / needs more time is long gone. Gert Doering -- NetMaster -- have you enabled IPv6 on something today...?
