Steps

Bypassing Spam Detection

Only the Approved IP Address tab

Select Bypass spam detection for approved IP addresses.

Searching IP Addresses

The Approved IP Address tab
The Blocked IP Address tab

Type an IP address in the search box.

Click Search.

Note

The search box has an auto-complete feature that you can use to manually type a CIDR block. In detail, Trend Micro Email Security autocompletes your input based on the CIDR addressing format if you accidentally type only the first several octets of an IP address before clicking Search.

For example, if you type 16 and click Search, Trend Micro Email Security automatically changes your input into 16.0.0.0/8 and lists all IP addresses whose first octet is 16.

Specify the IP address and type a description.
Click Save.

Importing IP Addresses

Click Import.
Next to File location, browse and select a CSV file to import.

Trend Micro Email Security verifies the file size and total number of lines in the file, and checks all the entries in the selected file to identify any invalid or conflicting IP addresses.
