Email block list
You can configure the FortiGate unit to tag all IMAP and POP3 protocol traffic sent
from unwanted email addresses. When the FortiGate unit detects an email sent from
an unwanted address pattern, the FortiGate unit adds a tag to the subject line of the
email and writes a message to the email filter log. Receivers can then use their mail
client software to filter messages based on the subject tag.
You can tag email from a specific sender address or from all address subdomains by
adding the top-level domain name. Alternatively, you can tag email sent from
individual subdomains by including the subdomain to block.
