I have setup an exchange server on premise with at SMTP Relay on our VPS. It works very well, unfortunately I’m a little confused as to where I setup the various permissions for SPAM.
All my incoming email receives
The error that the other server returned was:
550 5.7.1 Message rejected as spam by Content Filtering.
The only way to get around it is to add the domain as an authoritative as an accepted domain. Which I assume must be the incorrect way to add them.
So please someone tell me where it is I can setup who can email in via my SMTP server?
Thanks in advance

Based solely on the information given, examine your Content Filter configuration in Exchange Powershell:
