Tips for Postini Spam Filtering Using Approved Sender Lists

Prevent false positives in your spam filter with periodic reviews.

If you use All Covered's Email Protection Service, powered by Postini, follow these tips for your white list. Any email address on your Approved Senders list will not be quarantined for spam. An Approved Senders list helps prevent false positives, but they can also cause a vulnerability, because senders can "spoof" mail to falsify the sender address and bypass spam filtering.

Periodic reviews of the Approved Senders lists for your organization and users can help, especially if spoofed spam seems to be getting through filters more often.

End User Tip

As an end user, you can manage your Approved Senders list through the Message Center. Follow these steps:

1. Log into your Message Center.
2. Click on the Junk Email Settings link in the top left corner.
3. Scroll down to the Sender Lists area.
4. To add a sender, type in the person's full email address or the domain (ex: domain.com) and click Save to List.
5. To remove a sender, select that sender and click Delete from List.

Note: It is recommended that you add family, friends and work colleagues to the Approved Senders list so their messages will automatically by-pass the filters.
