Configuring System Settings

Adding a FortiSandbox unit

The FortiSandbox unit is used for automated sample tracking, or sandboxing. You can send suspicious email attachments to FortiSandbox for inspection when you configure antivirus profiles (see “Managing antivirus profiles” on page 521). If the file exhibits risky behavior, or is found to contain a virus, a new virus signature is created and added to the FortiGuard antivirus signature database. For more information about FortiSandbox, please visit Fortinet’s web site at http://www.fortinet.com.

Suspicious email attachments include:

  • Suspicious file detected by heuristic scan of the AV engine
  • Executable files and executable files embedded in archive files.
  • Type 6 hashes (binary hashes) of the spam email detected by FortiGuard AntiSpam Service

To add a FortiSandbox unit

  1. Go to System > Configuration > FortiSandbox.
  2. Enable the FortiSandbox.
  3. Enter the FortiSandbox host name or IP address. The port to use is 514. If you have a firewall in between FortiMail and FortiSandbox, make this port is allowed.
  4. For Statistics interval, specify how long FortiMail should wait to retrieve some high level statistics from FortiSandbox. The default interval is 5 minutes. The statistics include how many malwares are detected and how many files are clean among all the files submitted.

Customizing GUI, replacement messages and email templates

This section contains the following topics:

  • Customizing the GUI appearance
  • Customizing replacement messages
  • Customizing email templates

Customizing the GUI appearance

The System > Customization > Appearance tab lets you customize the default appearance of the web-based manager, per-recipient quarantine, and webmail pages with your own product name, product logo, and corporate logo.

You can customize the webmail interface language. If your preferred language is not currently installed, you can add it. You can also adjust the terms in existing language files. This can be useful for localizing terms within a language. For example, you could adjust the English language file to use spellings and terms specific to the locale of the United Kingdom, Australia, or the USA if your email users are most familiar with terminologies popular in those areas.

To access this part of the web UI, your administrator account’s:

  • Domain must be System
  • access profile must have Read-Write permission to the Others category

For details, see “About administrator account permissions and domains” on page 290.

To customize the GUI appearance

  1. Go to System > Customization > Appearance.
  2. Click the arrow to expand Administration Interface and Webmail interface.
  3. Configure the following to change appearance:

GUI item Description
Top logo Select change to upload a graphic that will appear at the top of all pages in the web UI. The image’s dimensions must be 460 pixels wide by 36 pixels tall.

For best results, use an image with a transparent background. Non-transparent backgrounds will not blend with the underlying theme graphic, resulting in a visible rectangle around your logo graphic.

Note: Uploading a graphic overwrites the current graphic. The FortiMail unit does not retain previous or default graphics. If you want to revert to the current graphic, use your web browser to save a backup copy of the image to your management computer, enabling you to upload it again at a later time.

Default language Select the default language for the display of the web-based manager.

You can configure a separate language preference for each administrator account. For details, see “Configuring administrator accounts” on page 294.

The message list organizes replacement messages into a number of types (for example, System, Reject, and so on). Use the expand arrow beside each type to display the replacement messages for that category. Double-click each replacement message to customize that message for your requirements.

You can reword existing messages or create new ones.

Modifying replacement messages

You can modify the text and HTML code within a replacement message to suite your requirements.

You can change the content of the replacement message by editing the text and HTML codes and by working with replacement message variables. For descriptions of the default replacement message variables, see “Default replacement message variables” on page 282.
