Figure 116:Protection profile spam filtering options
The following options are available for spam filtering through the protection profile.
See
“Spam filter” on page 343
for more spam filter configuration options.
IP address FortiGuard
check
Enable or disable the FortiGuard spam filtering IP address blacklist.
FortiGuard extracts the SMTP mail server source address and
sends the IP address to a FortiGuard server to see if this IP
address matches the list of known spammers. If the IP address is
found, FortiGuard terminates the session. If FortiGuard does not
find a match, the mail server sends the email to the recipient.
See
“FortiGuard-Antispam Service” on page 346
for more
information about this service.
URL FortiGuard check
Enable or disable the FortiGuard spam filtering URL blacklist.
FortiGuard checks the body of email messages to extract any URL
links. These URL links are sent to a FortiGuard 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, FortiGuard terminates the session. If FortiGuard does not
find a match, the mail server sends the email to the recipient.
See
“FortiGuard-Antispam Service” on page 346
for more
information about this service.
