Configuring spam filtering options
Figure 115:Protection profile spam filtering options
The following options are available for spam filtering through the protection profile.
See
“Spam filter” on page 333
for more spam filter configuration options.
IP address FortiShield
check
Enable or disable the FortiShield spam filtering IP address blacklist.
FortiShield extracts the SMTP mail server source address and
sends the IP address to a FortiShield server to see if this IP
address matches the list of known spammers. If the IP address is
found, FortiShield terminates the session. If FortiShield does not
find a match, the mail server sends the email to the recipient.
See
“FortiShield” on page 335
for more information about this
service.
URL FortiShield check
Enable or disable the FortiShield spam filtering URL blacklist.
FortiShield checks the body of email messages to extract any URL
links. These URL links are sent to a FortiShield server to see if any
of them is listed. Typically Spam messages contain URL links to
advertisements (also called spamvertizing). If a URL match is
found, FortiShield terminates the session. If FortiShield does not
find a match, the mail server sends the email to the recipient.
See
“FortiShield” on page 335
for more information about this
service.
