Email Blacklist & IP Blacklisting

Control the mail entering your inbox with an optional email blacklist or email whitelist of IP addresses. IP blacklisting works by adding an IP address to the blacklist, which stops that IP address from connecting to your server. Adding an IP address to the whitelist makes that IP a trusted sender. System Administrators can manually add/remove IP addresses from these lists. This is the more strict method; permanently blocking or allowing IP addresses until acted upon again by a System Administrator. The function can also be automatic; allowing or blocking senders for a certain amount of time based on abuse detection rules.
