Configuring incoming mail protection
The Incoming tab displays the antispam and antivirus settings for the protected domains, and enables you to change the default settings.
When your FortiMail unit operations in gateway or transparent mode, this tab also lets you set up SMTP server authentication for your email users, so that they can access their webmail or check their recipient quarantine folders. SMTP is not needed in server mode because in that mode the FortiMail unit is the mail server. (To set up authentication using another protocol, such as POP3, go to Profile > Authentication in advanced mode.)
To edit incoming antispam and antivirus settings
1. Go to Settings > AntiSpam > Incoming.
2. To change settings, do one of the following:
• select a domain in the table and click Edit
• double-click the domain
A dialog appears.
3. 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.
4. Select one of the following for the antivirus level:
• Unknown: No setting.
• Disabled: Virus checking is off.
• Enabled: Virus checking is on.
5. In gateway and transparent mode, configure an SMTP server connection under External SMTP Server Settings:
• Enter the fully qualified name or IP address of the SMTP server.
• Change the default SMTP server port if necessary. For example, for SMTP with SSL, this typical is 465.
• Select Server Requires Domain if the authentication server requires that email users authenticate using their full email address (such as user1@example.com) and not just the user name (such as user1).
• Select SSL if your server supports secure socket layers (SSL) and you want to encrypt communications between the FortiMail unit, and this server.
• Select Secure Authentication if you want to use secure authentication to encrypt the passwords of email users when communicating with the server.
• Select TLS if your server supports transport layer security (TLS) and you want to authenticate and encrypt communications between FortiMail and this server.
6. Click OK.
| 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. |
