tbh, I think this is only true to a small degree for DS-Lite approaches using MAP-T or NAT64. > That's why dual stack still is (and probably will be in the foreseeable > future) still a thing. I think you are very mistaken on that one, as dual stack complexity is significantly higher than single stack. > Nobody is setting up IPv6-only servers, unless they are experimental servers > meant to be used only by closed group of users, and not generally reachable > from the Internet.

I could send you quite some documents about IPv6 only hostings, but I believe that is really going too far offtopic. In a nutshell, IPv6 only hostings are much easier, more sustainable and the only thing that you need is a border gateway/translator, if communication to the IPv4 world is required. > [...] > Do you plan to add to your system some kind of gateways between the "secure > email" and the "normal email" world? > > If yes, that kinda defeats the purpose you are building it for.

There is a very easy yes-and-no at the same time answer here: - Within the "secure mail" network, there will be no connection to legacy systems - However operators can choose to connect their "normal email" system internally to securemail This way forwarding is not enabled, but legacy systems can interact with secure email systems, if the operator is able to reach out. So graphical seen: example.org (secure email) --[ internal ]--- example.org (normal email) | | | example.com (secure email only, allows access from example.org) Hope that makes sense. I can add further clarifications off list to keep it postfix focused. BR, Nico
