I am sorry for my ignorance. Is this something I can do locally, or
is this a command that I need to run on the remote SMTP server I am
trying to contact? If I can run this command locally, how do I
specify the remote server? Is there anything else I can do locally?
(I've made gnutls-cli more verbose and it gave me a lot of
information, though in the end nothing appeared useful to me to
resolve this problem.)

Though I can login on the SMTP server, I am not sure I found the
right certificate, and this file is not readable for ordinary users.
