Hi @Glenn Brown 

Thank you for posting your question in the Microsoft Q&A forum.   

Based on your inquiry, we understand that you have considered an Error announcement while configuring in anti-spam policies . We will be glad to assist you in this part.   

As my research,  may concern to Microsoft Defender configuration.   

However, I have found the article which relevant to your issue.  

Configure spam filter policies - Microsoft Defender for Office 365 | Microsoft Learn 

You could try these constructions to work around block senders and domain by using PowerShell: 

1.Connect to Exchange Online PowerShell

Install-Module -Name ExchangeOnlineManagement  

Import-Module ExchangeOnlineManagement 

Connect-ExchangeOnline 

2. To return a summary list of all spam filter policies run this command: 

Get-HostedContentFilterPolicy    

3.To return detailed information about a specific spam filter policy, use this syntax: 

Get-HostedContentFilterPolicy -Identity "the policy name" | Format-List  

4. You can set to put in the sender and domain in the list 

Set-HostedContentFilterPolicy -Identity "the policy nam" -BlockedSenderDomains @{add="company.com"} 

Please let me know if you need further assistance, please let us know.
