Port 465 is what libcurl implements as smtps://. I agree that it isn't

Yes, I added support for that old legacy style mostly because we already do
support ftps:// that way and it was very easy to do. I don't know if anyone
these days actually use that concept.
but the standard way to do it is to connect in the clear, issue the
STARTTLS command, and then upgrade to TLS.
Giving an example of how you do *that* would be a more useful thing to
do in a comment. Bonus points for mentioning that you would hopefully
expect this to be connecting to port 587 rather than port 25 (RFC4409).
I'll take a look. I think this could be better placed in a separate example
though.
Making two examples certainly isn't a bad idea, but perhaps this little tiny
option doesn't warrant a separate one? You make libcurl use STARTTLS by
setting the CURLOPT_USE_SSL option accordingly.
