Adding Senders
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.

In the Add Approved Senders
dialog box, type a sender in the second field. A sender can be a specific email address
or all addresses from a specific domain or subdomain.
-
Filter a specific email address by typing that email address.
-
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.
The following table displays format examples that are valid or not valid:
