Hello,
But I have no idea how to use the postfix tools to start a TLS
connection to such an server without sending an email. This requires
too much internal knowledge I fear. Last time I tried to call smtp
tool by hand it told me not to do so and I took that advice.
/usr/sbin/sendmail -f $(id -nu) -bv 'postmas...@example.com'
or via the "posttls-finger" utility from Postfix 2.11 source tarball.
Hmpf. It says "dane configured with dnssec lookups disabled". Seems I need
to fix the RPM first.
Ciao
