email is garbage

i run my own relay, which i am constantly adding and changing code on and restarting it, and other users are using it constantly
i set up a whitelist feature on it to stop that when i need to quiet them down but mostly it's a good thing because sometimes it shows me logs that i didn't see before
zbd is full of shit and the go-nostr library is a shitfight, i have cleaned it up and i'm mostly happy with the results now but i'm waiting a little while to test everything before i pop it out and present it as its own thing
