DoH plugin for BIND

In my experience and from what I've heard, very few. Even if your ISP 
allows it, chances are that other mail servers will reject it, since 
residential areas aren't really suited for and aren't generally used for 
long-term mail servers. I would recommend against running your mail 
server (directly) on your home connection. Here I rent 3 VPS's as pretty 
much edge servers and connect my mail, web, Gitea and other servers from 
there (possibly my DoT service as well since almost everything is 
already reverse proxied with nginx from there). VPN connections are made 
from all of those local servers to there but it's far from ideal (70 
servers x 3 VPN connections each and you've got 210 total.. and that's 
where I more or less screwed up). Nowadays I'd rather consider either 
making my VPS's connect to my home, or make a single server be the 
gateway at home that makes VPN connections to those VPS's instead. 
Probably the latter since home connections have dynamic IP's too.. that 
complicates things a bit.
