That does not work from here - I get:

didn't found starttls in server response, try anyway...


What do you see with

telnet 199.175.188.52 25
EHLO your.fqdn

Do they advertise starttls? Not for me:

telnet 199.175.188.52 25
Trying 199.175.188.52...
Connected to 199.175.188.52.
Escape character is '^]'.
220 mta2.spacex.com ESMTP
EHLO ns
250-mta2.spacex.com
250-8BITMIME
250-SIZE 209715200
250-AUTH PLAIN LOGIN
250 AUTH=PLAIN LOGIN


It is possible that 199.175.188.52 is really some load balancer, and
some of the devices behind it advertise starttls, and others don't.
