@BronGondwana Understood, thank you for taking the time to respond. Do we agree that in a world governed by JMAP, this would be easily achievable?

@nathan288573 No, not to a random host on the internet, because your typical home/office computer will likely have an outbound firewall blocking SMTP, plus it's unlikely to have all the right DNS records in place - and that's likely to get worse. You need to authenticate to a smarthost.

@BronGondwana As of today, is there a (simple) way to reliably send and receive email directly from a typical home/office computer to another computer or to traditional email providers using just your IP address or even a locally hosted server on a standard internet connection?
