Subject: 550 server without authentication error

We are running CommuniGate Pro v6.2.0 on a Red Hat linux server. When we try to send emails to a specific external address, their mail system replies with the following delivery failure:

 

Failed to deliver to 'xxxxx@bcsaust.com.au'

SMTP module(domain bcsaust.com.au) reports:

host bcsaust.com.au says:

550 server without authentication.

 

At this point in time this is the only external email domain that we are sending to which is reporting this problem.

Are there any settings I can check on our CommuniGate Pro server?
