Trend Micro Email Security approves or blocks email messages from the specified sender for the entire organization, a managed domain, or a specific recipient address in your managed domains.
For example, after adding spammerbob@examplespamdomain.com to the blocked list for your managed domain mydomain.com, Trend Micro Email Security only blocks the email messages sent from spammerbob@examplespamdomain.com to addresses in the mydomain.com domain. Trend Micro Email Security still scans and possibly passes email messages sent from spammerbob@examplespamdomain.com to your other managed domains.

Filter all addresses from a domain by using an asterisk (*) to the left of the at sign (@) in the email address. For example, *@example.com will filter all email addresses in the example.com domain.
-
Filter all addresses from a subdomain by using an asterisk (*) to the left of the at sign (@) and also using an asterisk (*) in place of the subdomain in the email address. For example, *@*.example.com will filter all email addresses in all subdomains of the example.com domain.
