Configuring AntiSPAM Settings

Configuring the personal black lists and white lists

AntiSpam > Black/White List > Personal lets you add or modify email users’ personal black or white lists in order to block or allow email by sender. It also lets you back up and restore the per-user black lists and white lists.

In addition to FortiMail administrators configuring per-user black lists and white lists, email users can configure their own per-user black list and white list by going to the Preferences tab in FortiMail webmail. For more information, see the online help for FortiMail webmail.

Use black and white lists with caution. They are simple and efficient tools for fighting spam and enhancing performance, but can also cause false positives and false negatives if not used carefully. For example, a white list entry of *.edu would allow all email from the .edu top level domain to bypass the FortiMail unit’s other antispam scans.

To access this part of the web UI, your administrator account’s access profile must have Read or Read-Write permission to the Black/White List category. For details, see “About administrator account permissions and domains” on page 290.

To view and add to personal black lists or white lists

  1. Go to AntiSpam > Black/White List > Personal.

Configuring the black list action

The Blacklist Action tab lets you configure the action to take if an email message arrives from a blacklisted domain name, email address, or IP address.

The FortiMail unit will apply this action to email matching system-wide, per-domain, and per-session profile black lists.

To access this part of the web UI, your administrator account’s access profile must have Read or Read-Write permission to the Black/White List category. For details, see “About administrator account permissions and domains” on page 290.

Domain administrators can configure the black list action, and therefore could affect domains other than their own. If you do not want to permit this, do not provide Read-Write permission to the Black/White List category in domain administrators’ access profile.

To configure black list actions

  1. Go to AntiSpam > Black/White List > Blacklist Action.

Figure 275:Configuring the black list action

  1. Select one of the following:
    • Reject: Reject delivery of the email and respond to the SMTP client with SMTP reply code 550 (Relaying denied).
    • Discard: Accept the email, but silently delete it and do not deliver it. Do not inform the SMTP client.
    • Use AntiSpam profile setting: Use the actions configured in the antispam profile that you selected in the policy that matches the email message. For more information on actions, see “Configuring antispam action profiles” on page 516.
  2. Click Apply.
