BLACK LIST

Connections and messages will be refused if they come from addresses or domains, which are listed in the blacklist. The blacklist can be defined manually or imported from an address file. It can also be exported to a specified file. Use the Black List screen to configure your blacklist.

Adding an IP or subnet address to the blacklist

You can block either a single IP or a block of IPs by using the Subnet Mask:

•Adding a single IP address such as 10.1.4.2 will deny messages from one IP address.

•Adding a block such as 10.1.4.0/24 will deny messages from a group of IP addresses.
