Postini Anti-Spam & Anti-Virus

All of our Exchange email services use Postini filtering for anti-spam and anti-virus protection. By default all Exchange users have these features enabled. End users and administrators have the ability to manage the anti-spam settings. End users only have the ability to manage their own settings while Administrators can manage the settings for the entire organization.

Postini Control Panel

To manage your spam filter settings you are provided with a control panel at Postini. Through the control panel you can view and messages that were caught by your spam and junk filters. If you locate a message that was caught in the filters you can choose to have that message delivered to you with a simple click of a button. You can also use the control panel to manage settings such as approved and blocked senders. This will allow you to approve or deny senders based on email address or if you prefer you can approve or deny senders based off of the domain they are sending from.

Accessing Postini Control Panel

You can access this two ways. The first method is to type https://login.postini.com into the address bar of your web browser and then use your email address and password to log in. The second option is accessing it through your myhosting.com Control Panel. This method passes your login credentials so you don't have to type them in. To access the Postini control panel via the myhosting.com control panel you would do the following.

  1. Log into your account's control panel.
  2. Select your hosting subscription from the subscription drop-down box.
  3. Next click on the "Exchange Email" tab.
  4. Click on the display name you want to manage.
  5. Then click on the "Protection" tab.

End User Management

Each user by default has the ability to manage their own Postini settings such as Approved and Blocked senders lists.

Approved Senders (User Level)

The first step in setting up an approved senders list is to log into your Postini control panel.

  1. Once you've logged into the Postini control panel you will first click on the "My Settings" link at the top right-hand side of the site.

In addition to allowing specific email addresses you can enter a domain into the "Approved Domains" section. Once you've entered the addresses and domains make sure to press the related "Update" buttons to save your changes.

Postini on Distribution Lists

By default, Postini protection is also enabled for Distribution Lists. This ensures that your Distribution List email addresses are also protected. If an email is quaranteened by Postini for a Distribution List, the quarantine notice is sent to the list itself. However this may cause issues, because the recipients of the email itself may not be able to access the quarantine for that mailbox. In order to check the quarantine for a distribution list, please contact the account administrator for your domain who should be able to access the quarantine from their Admin panel.

As an alternative, you may wish to disable Postini protection for your Distribution List. If the distribution list is configured only to receive email from your Organization or from the Distribution List Members, then this is the suggested, since SPAM and Viruses are less likely in these cases.

  1. From your Exchange Email panel, click on Distribution Lists.
  2. Select the distribution list you wish to modify from the list.
  3. Click on the Protection tab, then click on Disable.

This will remove Postini protection entirely from the selected distribution list.
