Incoming emails being rejected as spam

I am getting reports from colleagues that when emails are being sent to my plusnet address they are getting a spam notification that I did not want their email. Error message as below:-

The following recipient(s) cannot be reached:
 on 28/08/2020 10:55

            Diagnostic code = NoDiagnostic; Reason code = TransferFailed; Status code = 500

            < ( #5.0.0 smtp;552 Spam Message Rejected>

I have tried sending an email from my gmail account and the message is getting through but I am getting a bouncback "Mail Delivery subsystem" email saying

"There was a problem delivering your message to See the technical details below, or try resending in a few minutes.

There is an attached text document that says

"Reporting-MTA: dns;

Arrival-Date: Fri, 28 Aug 2020 05:15:44 -0700 (PDT)
X-Original-Message-ID: <03c101d67d34$f3da9c10$db8fd430$>

Final-Recipient: rfc822;

Remote-MTA: dns; (, the server for the domain
Diagnostic-Code: smtp; 552 Spam Message Rejected
Last-Attempt-Date: Fri, 28 Aug 2020 05:15:48 -0700 (PDT)"

I have checked my spam settinmgs and they are set to the lowest level 1.

Any help/advice would be appreciated.

@JW is there enough information here for a look at the diagnostic in-bound logs please?
