 * when postman connects to the mailserver in question all goes well as long as 
   tls v1.0 is enabled in postfix, for security reasons tls v1.0 needs to be disabled
   but that seems to result in postman not being able to connect to the mailserver…
   is this expected behaviour? if not, any ideas on how to get it working? below
   is the session transcript of a failed connection attempt with tls v1.0 disabled
   in postfix (not too much to view):
 * smtp:tls:plain://xxx.eu:587
    220 xxx.eu ESMTP Postfix (Debian/GNU) EHLO mywordpresssite.
   com 250-xxx.eu 250-PIPELINING 250-SIZE 20971520 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES
   250-8BITMIME 250 DSN STARTTLS 220 2.0.0 Ready to start TLS
