IP address Spam filter
IP address
The FortiGate unit uses the IP address list to filter incoming email. The FortiGate unit
compares the IP address of the sender to the list in sequence. If a match is found, the
corresponding protection profile action is taken. If no match is found, the email is
passed on to the next spam filter.
You can enter an IP address and mask in two formats:
• x.x.x.x/x.x.x.x, for example 62.128.69.100/255.255.255.0
• x.x.x.x/x, for example 62.128.69.100/24

IP address list
You can configure the FortiGate unit to filter email from specific IP addresses. You
can mark each IP address as clear, spam, or reject. You can filter single IP
addresses, or a range of addresses at the network level by configuring an address
and mask.
