Support STARTTLS in SMTP and STLS in POP3. This includes the sendmail thread. Clients can now be configured to use STARTTLS with Synchronet mail services, and Synchronet will attempt to deliver securely when possible (though it will fall back to plain text delivery when necessary.) This touches a *lot* of mail server stuff, so some instability is not unlikely. Of course, RFC8314 (Jan, 2018) officially recommends implicit TLS on the TLS ports now, so support for that should be next.
