Sorry, no, I meant your goal of allowing overriding config sounds like a
reasonable thing to want. But from reading your message below, it seems
that is not actually the problem you are trying to solve.

Hmm. From your description and the patch, I thought that was something
introduced by your patch. But looking at the existing code, it seems
like that is already the case. IOW, I don't understand why
"--smtp-encryption=none" does not already work looking at the current
code.
So being more careful about typos is an improvement we could make, but
it is not a feature that would need to be part of a bugfix patch.

Right. I meant that you should introduce "none" as an explicit "no, I
don't want this" and die when the flag is not one of {ssl, tls, none}.

Ah, I see. I misunderstood the original problem you were trying to solve
(I thought your example was "see? Encryption is off, so the server won't
do AUTH, demonstrating that the patch works.").
Overriding the smtp user from the config is a separate issue, and I
don't think that is currently possible. The usual way to spell an option
like that in git is "--no-smtp-user", but it seems that we use perl's
GetOptions, which does not understand that syntax. So you'd have to add
a "--no-smtp-user" by hand.
