Configuring outgoing mail protection
After you have created a protected domain, the FortiMail unit will apply default outgoing antispam and antivirus settings to the protected domain. The Outgoing tab enables you to customize these default settings.
To edit outgoing antispam and antivirus settings
1. Go to Settings > AntiSpam > Outgoing.
2. Select one of the following for the antispam level:
• Unknown: No setting.
• Off: No scanning.
• Low: Spam detection is on low but with a good detection rate and little impact on system performance.
• Medium: Spam detection is on low but with a better detection rate, but with a small impact on system performance.
• High: Spam detection is on low but with the best detection rate, but with a higher impact on system performance.
3. Select one of the following for the antivirus level:
• Unknown: No setting.
• Disabled: Virus checking is off.
• Enabled: Virus checking is on.
5. Click Apply.
| The levels for antispam and antivirus could contain the value Advanced instead on those listed. This means they were set in advanced mode using options not available in basic mode. |
Configuring access control
Access control rules allow specific SMTP clients to send email from your protected domains. These rules prevent your FortiMail unit from being an open relay. Open relays are often used by spammers, which could cause your unit to be blacklisted by other mail servers.
Access control rules allow, discard, reject, or relay email based on the sender, recipient, IP address, or a reverse DNS lookup of the domain name of the connecting SMTP server.
To configure access control
1. Go to Settings > AntiSpam > Outgoing.
2. Click Access control link.
A new window appears. If you created an access control rule using the Quick Start Wizard, it will appear on the list.
3. Either click New to create a new rule, or select an existing rule and click Edit.
A dialog appears.
5. Click Create or OK.
