Creating an allowed senders filter list
Applies to: Forefront Protection for Exchange
Forefront Protection 2010 for Exchange Server (FPE) provides allowed senders lists so that you can maintain lists of safe e-mail addresses or e-mail domains that are not subjected to filtering. (The allowed sender lists have no effect on scanning for malware and can only be used with the transport scan job.) FPE checks the sender address or domain against the allowed senders list. If the e-mail address or domain appears on the allowed senders list, FPE bypasses all filtering that has been enabled for the list.
Allowed senders filter lists allow specified senders to bypass filtering. However, you cannot bypass filtering for recipients.
To create an allowed senders filter list
In the Forefront Protection 2010 for Exchange Server Administrator Console, click Policy Management, and then under the Filters section, click Filter Lists.
In the Filters – Filter Lists pane, click the Create button.
In the Select Filter Type dialog box, select Allowed senders and then click Next.
In the Filter Details dialog box, specify the filter list name and filter details:
In the Filter list name box, type a name for the new list.
In the Filter criteria box, type the e-mail address or e-mail domain to be included in the filter list, and then click Add.
User addresses should be entered in the following format: firstname.lastname@example.org
E-mail domain names should be entered in the following format: domain.com, domain.edu, domain.org, and so on.
You can repeat this process in order to add multiple addresses or domains, or you can add multiple items on the same line, provided that they are separated by a comma.
You can edit items in an allowed senders filter list by double-clicking the item, editing the item, and then pressing ENTER. You can delete items from an allowed senders filter list by selecting the item and clicking Remove. You can also import items into an allowed senders filter list (for more information, see Importing items into a filter list), and export items from an allowed senders filter list (for more information, see Exporting items from a filter list).
To configure the filtering options that will be bypassed for the e-mail addresses or domains specified in the list, you can select the following check boxes:
**File—**Skips file filtering.
**Keyword—**Skips keyword filtering.
**Content—**Skips subject line and sender-domain filtering.
In the Target dialog box, configure how you want the filter list to be applied to the Hub/Edge Transport Scan:
To enable the filter list for use with the transport scan, using the Enabled drop-down list, select Yes (this is the default).
The filter list you just created appears on the Filters – Filter Lists pane.
