Ah, OK. So is LIST EXTENSIONS the best way to illustrate this or should
I insert a GROUP local.public (which I just noticed isn't included in
that example)? Or should I do both? Three proposed examples are shown
below.
[C] STARTTLS
[S] 382 Continue with TLS negotiation
[TLS negotiation is attempted here]
[Following failed negotiation, traffic resumes without TLS]
[C] GROUP local.confidential
[S] 483 Encryption or stronger authentication required
[C] LIST EXTENSIONS
[S] 202 Extensions supported:
[S] STARTTLS
[S] OVER
[S] .
[C] GROUP local.private
[S] 400 Closing connection due to lack of security
[C] STARTTLS
[S] 382 Continue with TLS negotiation

[Following failed negotiation, traffic resumes without TLS]
[C] GROUP local.confidential

[C] GROUPS local.public
[S] 211 321 4000 4321
