How's your self hosted email going? Any advice you can share to avoid some of the major issues?

Happy to hear that accuracy is improving

Interesting! You said you gave up on the outbound, does that mean you can't reply to mails you receive? But if you can reply, does that mean the sender (let's assume someone with gmail) will get it or would even that likely end up blackholed or in spam?

Stop tempting me! I might do it.

One question, I currently use proton mail to use my domain for email and there are no issues afaik. Do you think a few years of using proton will have "whitelisted" my domain enough or will all the issues pop up once I change to hosting it myself?

Tomato, tomatoe, as long as they're stuck on the boat

Ah nice, that is a great idea. I will try this out, thanks!
