Use the Enable Anti-spam Updates wizard to enable anti-spam updates on computers that have the Microsoft Exchange Server 2007 Edge Transport server role or the Hub Transport server role installed. By using this wizard, you can determine the type of Microsoft Forefront Security for Exchange Server anti-spam updates that are retrieved and set the mode by which the anti-spam updates are retrieved.

Update mode
  • Manual   Select this option if you want to manually apply content filter updates from Microsoft Update.

  • Automatic   Select this option if you want anti-spam updates that are retrieved from Microsoft Update to be applied automatically.

    Note:
    Automatic mode is a premium feature. If it is enabled, Automatic mode requires either an Microsoft Exchange Enterprise Client Access License (CAL) for each user mailbox or Forefront Security for Exchange Server. You must select Automatic mode for Spam signature updates and IP Reputation Updates to be available.
    • Spam signature updates   Spam signature updates may be downloaded several times a day to supplement the content filter accuracy.

    • IP Reputation updates   IP Reputation updates may be downloaded several times a day to improve the accuracy of sender reputation information about IP addresses that are known to send spam.

Update service

Select this option to agree to enable Forefront Security for Exchange Server anti-spam updates via Microsoft Update. Users must opt in to using Microsoft Update so that Forefront Security for Exchange Server anti-spam updates published on Microsoft Update are visible to the Exchange server. If you don't select this option, you cannot enable Forefront Security for Exchange Server anti-spam updates via Microsoft Update.

Note:
The Forefront Security for Exchange Server anti-spam update service polls Microsoft Update several times a day to download updates or determine whether the opt-in status has changed. Therefore, it may take up to one hour or more for the opt-in action to be reflected in your system. If you want to verify the modified opt-in status immediately, restart the Microsoft Exchange Anti-spam Update service.
