@RatulaC the recommendation should be to use antispam block list if they want to block spam and if they want to block everything else from the sender use Domains & addresses (Sender ) block in Tenant allow/Block list.

[chrisda]

I added the following note to the domains and email addresses bullet:

[!NOTE] To block only spam from a specific sender, add the email address or domain to the block list in anti-spam policies. To block all email from the sender, use Domains and email addresses in the Tenant Allow/Block List.

Thanks for the feedback.
