Comment on Good mail server for selfhosting
muntedcrocodile@lemm.ee 2 months agoI’ve heard that using ddns for mail gets u into all sorts of IP blacklisting issues. I don’t even have a non cgnat iv4 and I’m not sure if email can work with an ipv6 only

Yes thats why i said in theory. I doubt that many residential IPs are blacklisted, but still not optimal.
IPv6 only works but there are probably many Mail Servers that are IPv4 only, so you will not receive mails from them.
If you are serious about it, rent a VPS or get a static IP on your residential connection.
