 Options for protecting distribution lists within Postini
 Protect Your Mailing and Distribution Lists You can protect mailing and distribution lists from spam and viruses. These lists are addresses that deliver a message from outside your network to a group of people in your domain, such as partners@your_domain.com, or noon_cyclers@your_domain.com. Often, when users complain about spam passing through, they are receiving the spam through their membership in a mailing list. To protect a mailing list from spam and viruses, alias the mailing list to an existing or new user account. Do not add the mailing list as a user account. Under these circumstances, the mailing list is treated as a user, and all members of the mailing list, including those outside of your organizat

 How can I view the Postini log files for my domain?
 Run a Log Search    From the Log Search tab in the Administration Console, you can run queries based on the following criteria. Many log searches include the date range, sender, and/or recipient only; but you can also narrow your search by specifying inbound or outbound traffic, as well as the message disposition and other criteria:         Date range: This range corresponds to the time zone for the organization in which you’re running the search. Select a date range that matches the date and time the message was sent. You can use a date range such as Today, Yesterday, Last 7 days, or Last 30 Days.    The time zone for an organization is displayed adjacent to the search fields -- for example, America/New_York. This format specifies a country or world region, followed by a specific location within that region.    
 What are the approved/blocked sender list limits within Postini?
 The maximum number of characters for each approved/blocked list in the Administration Console is 4000. If each address or domain is 30 to 40 characters, each sender list can include approximately 100 to 130 addresses and domains. The maximum number of characters for all lists for each user in the Message Center is 1000. For each address, add an additional 2 characters to get an accurate count. If you run out of space and attempt to add another address, you receive an error similar to this: List length limit (4000) exceeded To free up more space, delete addresses that are no longer used.
