Allowed senders lists

Applies to: Forefront Security for Exchange Server

Forefront Security for Exchange Server provides allowed senders list functionality to permit administrators to maintain lists of safe e-mail addresses that are not subjected to filtering by the Transport Scan Job. (The allowed sender lists have no effect on scanning for viruses.) Forefront Security for Exchange Server checks the sender address against the allowed senders list. The sender address is defined by the General Options setting Transport Sender Information (either Use MIME From: Header (the default) or Use Transport protocol MAIL FROM). If the e-mail address or e-mail domain appears on the allowed senders list, Forefront Security for Exchange Server will bypass all filtering that has been enabled for the list.

To create an allowed senders list

  1. In the FILTERING section of the Shuttle Navigator, select Filter Lists.

  2. In the List Type section, select Allowed Senders.

  3. In the List Names section, click the Add button, type a name for the new list in the text box provided, and then press ENTER to save the list.

  4. With the new list name selected, click the Edit button. The Edit Filter List dialog box appears. Use it to enter e-mail addresses or e-mail domains to include in the allowed sender list.

  5. In the Include In Filter section, click the Add button. Type the e-mail address or domain in the text box, and press Enter. User addresses should be entered in the format: user@domain. E-mail domain names should be entered in the format: *domain.

  6. Enter each address or domain individually.

  7. When you are finished adding items, click OK.

  8. Click Save to save the list.

  9. To enable the list, click Allowed Senders in the FILTERING section of the Shuttle Navigator, select the Transport Scan Job, select the list name in the Sender Lists work pane, and set the List State to Enabled.

  10. In the Skip Scanning for section, indicate if the allowed senders list should apply to Keyword Filtering, File Filtering, or both. You can click All Types to have all the choices selected. If you make no choice, the filter is effectively disabled.

  11. Click Save.
