SpamTitan allows you to add display names of users to protect them from spoofing attempts.
Note
Even if you have enabled Display Name anti-spoofing, it is necessary to upload the display names of users you want to protect in order for display name anti-spoofing to be applied.
Once you have enabled Display Name anti-spoofing, follow the instructions below to add display names.
If you already have display names and they are not yet enabled for anti-spoofing, see Enabling Display Name Anti-Spoofing.
Go to the customer level, and from the side-bar menu, select Filtering > Anti-Spoof. Select the Display Name Anti-Spoofing tab at the top.
Your domains are listed in the table with the following details:
Domain: Domain name.
Status: Indicates whether display name spoofing is enabled for the domain.
Last updated: Date and time that the domain was last updated.
Locate the domain that you want to enable display name anti-spoofing for and select it. The Display Name Anti-Spoofing Data slideout appears.
Use the Search field to locate display names currently associated with this domain.
Select the Column icon to hide or view columns
Select the Add Users tab to add one or more display names. The users associated with these display names will be protected by anti-spoofing.
Add Single Users
Add Multiple Users
Select Add Multiple Users to upload multiple display names and their email addresses at one time, using a CSV file.
If you don't already have a list of users, you can go to your Microsoft Entra ID portal and export users from there. You can do so by selecting All users > Download users. Alternatively, you can go to your Group Members section, and select Bulk operations > Download members. Both options will provide a CSV file for download.
Once you have your list of users, you'll need to download the CSV template, by selecting it in Step 1, as shown below.
Save it and populate it with the display name data from the Entra ID file you downloaded. Note that the CSV template only requires Display Names and Email Addresses, so you will need to extract only this data from the Entra ID file.
Upload your new CSV file by clicking in the indicated area in the UI.
Locate the file in the pop-up window or drag and drop it from your folder.
After you've added display names, they'll appear in the display name list.
