Configuring a protection profile Firewall Protection Profile Spam filtering options Figure 216:Protection profile spam filtering options Note: NNTP options cannot be selected. Support will be added in the future. The following options are available for spam filtering through the protection profile. FortiGuard Antispam IP address check URL check E-mail checksum check Spam submission Enable or disable the FortiGuard Antispam filtering IP address blacklist. FortiGuard Antispam extracts the SMTP mail server source address and sends the IP address to a FortiGuard Antispam server to see if this IP address matches the list of known spammers. If the IP address is found, FortiGuard Antispam terminates the session. If FortiGuard Antispam does not find a match, the mail server sends the email to the recipient. See “FortiGuard Antispam Service” on page 187 for more information about this service. Enable or disable the FortiGuard Antispam spam filtering URL blacklist. FortiGuard Antispam checks the body of email messages to extract any URL links. These URL links are sent to a FortiGuard Antispam server to see if any are listed. Spam messages often contain URL links to advertisements (also called spamvertizing). If a URL match is found, FortiGuard Antispam terminates the session. If FortiGuard Antispam does not find a match, the mail server sends the email to the recipient. See “FortiGuard Antispam Service” on page 187 for more information about this service. Enable or disable the FortiGuard Antispam email message checksum blacklist. If enabled, this filter calculates the checksum of an email message and sends this checksum to the FortiGuard servers to determine if the checksum is in the blacklist. The FortiGate unit then passes or marks/blocks the email message according to the server response. When enabled, all e-mail messages marked as spam have a link added to the message body. If an email message is not spam, simply click the link in the message to inform FortiGuard of the false positive. FortiGate Version 3.0 MR5 Administration Guide 336 01-30005-0203-20070830
Firewall Protection Profile Configuring a protection profile IP address BWL check HELO DNS lookup E-mail address BWL check Return e-mail DNS check Banned word check Spam Action Append to Append with Black/white list check. Enable or disable the checking incoming IP addresses against the configured spam filter IP address list. (SMTP only.) IP address BWL check drop-down list: Select which IP address black/white list will be used with this protection profile. Enable or disable looking up the source domain name (from the SMTP HELO command) in the Domain Name Server. Enable or disable checking incoming email addresses against the configured spam filter email address list. E-mail address BWL check drop-down list: Select which email address black/white list will be used with this protection profile. Enable or disable checking that the domain specified in the reply-to or from address has an A or MX record. Enable or disable checking source email against the configured spam filter banned word list. Banned word check drop-down list: Select which banned word list will be used with this protection profile. Threshold: If the combined scores of the banned word patterns appearing in an email message exceed the threshold value, the message will be processed according to the Spam Action setting. See “Viewing the antispam banned word list” on page 447 for details. Action the spam filter will take. Tagged allows you to append a custom tag to the subject or header of email identified as spam. For SMTP, if you have virus scan or streaming mode (also known as splice) enabled, you will only be able to discard spam email. (Note that streaming mode is enabled automatically when you enable virus scanning.) Discard immediately drops the connection. Without streaming mode or scanning enabled, you can chose to tag or discard SMTP spam. You can tag email by adding a custom word or phrase to the subject or inserting a MIME header and value into the email header. You can choose to log any spam action in the event log. Append the tag to the subject or MIME header of the email identified as spam. Enter a word or phrase (tag) to append to email identified as spam. The maximum length is 63 characters. Note: Some popular email clients cannot filter messages based on the MIME header. Check email client features before deciding how to tag spam. See “Antispam” on page 443 for more spam filter configuration options. To configure the FortiGuard Anti-spam service, see “Configuring the FortiGate unit for FDN and FortiGuard services” on page 188.
