I'm writing up documentation and want to ensure that I'm using proper terminology.
1) What is the proper technical term for the SMTP tunnel encryption standard that typically starts on TCP/25, involves checking ESMTP capabilities for 250-STARTTLS and issuing the
STARTTLS command (followed by negotiation, public cert exchange, etc)?
2) Likewise, what is the proper technical term for SMTP tunnel encryption that uses port TCP/465 and requires negotiation immediately
I've always just called #1 "TLS Encryption"/"TLS" and #2 "Secure SMTP"/"SMTPS" but I don't think that's accurate.
