I just tried removing:

reject_unauth_destination, reject_non_fqdn_recipient

to leave me with:

smtpd_recipient_restrictions = permit_mynetworks

and now the message sending just hangs, sits there and eventually times out whilst trying to connect to the mail server.

I must point out that I'm trying to set this up so that we can have all mail leave thru this Centos box via the smtp server before going through the firewall.

Regards.
