Hi,
try to use the host-name instead of the IP and check your dns configuration (Cannot resolve PTR record for 10.16.56.20).
(Relaying temporarily denied) -> Some mail-servers are configured to accept only messages for their domain, e.g. mailserver mail.dummy.com only accepts messages to account with name like [email protected]
