virus-db {default | extended | extreme}

Depending on your models, FortiMail supports three types of antivirus databases:

• default: The default FortiMail virus database contains most commonly seen viruses and should be sufficient enough for regular antivirus protection.
  For the current release, FortiMail VM00 model supports the default virus database only.
• extended: Some high-end FortiMail models support the usage of an extended virus database, which contains viruses that are not active any more.
  FortiMail VM01/VM02/200F/400F models support both the default and extended virus databases.
• extreme: Some high-end models also support the usage of an extreme virus database, which contains more virus signatures than the default and extended databases.
  For the current release, FortiMail VM04/900F and above models support all three types of virus databases.

virus-outbreak {disable | enable | enable-with-defer}

When a virus outbreak occurs, it takes some time for updates to the FortiGuard Antivirus database. Therefore you can choose to defer the delivery of a suspicious email messages, giving time for the update to occur, and then scan the email again.

• disable: Do not query FortiGuard antivirus service.
• enable: Query FortiGuard antivirus service.
• enable-with-defer: If the first query returns no results, defer the email for the specified time and then query again.
