Julien ÉLIE <julien at trigofacile.com> added the comment:
Regarding these two possibilities, please note that the first one is discouraged (per RFC 4642).
STARTTLS is the preferrable way to start a TLS session.
In some existing implementations, TCP port 563 has been dedicated to
NNTP over TLS. These implementations begin the TLS negotiation
immediately upon connection and then continue with the initial steps
of an NNTP session. This use of TLS on a separate port is
discouraged for the reasons documented in Section 7 of "Using TLS
with IMAP, POP3 and ACAP" [TLS-IMAPPOP].
