I haven't been able to try this for the simple reason that I haven't
been able to find out where OS X stores its certificates...

Well, right now, --insecure is the only thing that does work. What
puzzles me is that --tofu should also work, from what I read about it,
but it doesn't. The connection appears to be established, but the mail
is not sent and the connection remains open, it seems.

and how would I go about doing that? :-)
