To add an address to the Anti-Spam address denylist:
Perform the following steps in the Management Console tree:
If you want to create an address denylist for an unassigned Security Server, expand the node of the relevant Security Server.
If you want to create an address denylist for Security Servers belonging to a profile, expand the Profiles node. Within this node, expand the node of the profile for whose Security Servers you want to create the address denylist.
Select the Server protection node.
In the workspace, on the Protection for the Transport Hub role tab, expand the Black list of Anti-Spam addresses configuration section.
To add a new sender address to the list:
Click the Add sender button.
In the Black list record settings window that opens, define the following settings:
Adding message senders to the denylist based on an email address or email address mask. Anti-Spam will assign the Address blacklisted status to messages that have been sent from the specified email addresses and perform on them actions configured for messages with this status.
Adding a sender to the denylist based on an IP address. Anti-Spam will assign the Address blacklisted status to messages that come from the specified IP address and perform on them actions that have been configured for messages with this status.
