Configure the Real-Time Blacklist
Blacklist providers are organizations that collect IP addresses of verified open SMTP relays
that might be used by spammers as media for sending spam. These known spam relays are
compiled by blacklist providers and are made available to the public in the form of real-time
blacklists (RBLs). By accessing these RBLs, the UTM can block spam originating from known
spam sources.
By default, the UTM comes with two predefined blacklist providers: Spamhaus and Spamcop.
There is no limit to the number of blacklist providers that you can add to the RBL sources.
To enable the real-time blacklist:
1. Select Application Security > Email > Real-time Blacklist. The Real-Time Blacklist
screen displays:
Figure 112.
2. To enable the Real-Time Blacklist function, select the Enable check box.
3. Select the Active check boxes to the left of the default blacklist providers (Spamhaus, and
Spamcop) that you want to activate.
4. Click Apply to save your settings.
To add a blacklist provider to the real-time blacklist:
1. In the Add Real-Time Blacklist section, add the following information:
In the Provider field, add the name of the blacklist provider.
In the RBL Domain Suffix field, enter the domain suffix of the blacklist provider.
2. Click the Add table button in the Add column. The new blacklist provider is added to the
real-time blacklist, and it is disabled by default.
