IPv6 (at least between the bridge and the PM servers)
IPv6 adoption is growing faster than it used to and has reached 25 %. It's high time you implemented IPv6, at least between the ProtonMail Bridge + App and your servers. Providers like UPC already dumped native IPv4 and offer only Carrier grade NAT.
