Consider looking into the certificate comments at READING.Debian.gz. In
case you are not running a Debian derivative, you might search for it on
the web.
openssl-s_client and openssl-s_server, as well as swaks, are useful for
debugging.
Making the whole system treats self signed certificates in the same manner
as it treats other certificate authorities is distribution dependent.
