> Would this mean integrated WKD (Web Key Directory) support for PGP? Didn't know of that, thanks. I think this could be used to encrypt submitted messages before trying to deliver them? What I had in mind when I wrote that line, was server-side signing. But I don't think it's such a great idea to have private keys on a server. It would be convenient for use with email clients that don't support signing themselves. But I don't use PGP or S/MIME myself at the moment. So my messages get stored in plaintext, are typically transferred over TLS (might want to start enforcing that!). With SPF/DKIM/DMARC and with SMTP (submission) authentication, sender addresses aren't typically forgable anymore, so signing is perhaps less important than it once was.
