Implicit TLS for SMTP Submission https://www.rfc-editor.org/rfc/rfc8314.html#section-3.3 And it's in the IANA registry of ports: https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?&page=9 So "smtps" is dead. Long live "submissions". But it isn't for server-to-server use. cheers, raf
