Take a look again at my commit message for 01/12:

	The 'host:port' form of argument for --smtp-server was only
	working for SSL connections, because the SSL connection code
	was relying on undocumented behavior of Net::SMTP::SSL (really,
	undocumented behavior of Net::SMTP's new method)...

Clearly my beef is with Net::SMTP--->::SSL<---

I touch upon this in the commit message for 06/12:

	The code could even be simplified further, because Net::SMTP{,::SSL}
	both take the PORT variable in their new methods (which, as of this
	commit, are actually the same method). Moreover, both take a server
	URI of the form 'host:port' that trumps any value passed to PORT.

	Unfortunately, none of this is documented publicly, so it isn't
	exploited out of purity.

Net::SMTP doesn't document the PORT key, even though it's the one that
implements the constructor for both Net::SMTP and Net::SMTP::SSL. Also,
Net::SMTP:SSL doesn't document whether PORT shadows the ':port' in any
'host:port' input.

So... I remain resolved in my stance: The documentation is poor and
"--smtp-server host:port" only worked because the code relies on the
undocumented behavior of the ':port' taking precedence of over any
PORT specification.

Actually, I think I read it too carefully and thought about it too much.

That's OK. I tend to sound harsher than I want as well.

I appreciate that remark; I'm admittedly not important, but I hope that
I'm at least useful.

Now let's get back to work!
