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.
- Log into your account's control panel.
- Select your hosting subscription from the subscription drop-down box.
- Next click on the "Exchange Email" tab.
- Click on the display name you want to manage.
- Then click on the "Protection" tab.
- Next you will need to log into the Postini control panel. You can do this by clicking on the "https://login.postini.com/exec/login" link.
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.
- 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.
- Next click on the "Approved Senders" link under the Junk Settings section.
- You'll then be able to enter an email address into the
"Approved Senders" or "Approved Mailing Lists" sections. 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.
Blocked Senders (User Level)
To set up a blocked senders list is you will first need to log into your Postini Control Panel.
- 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.
- Next click on the "Blocked Senders" link under the Junk Settings section.
- You'll then be able to enter an email address into the
"Blocked Senders" or a domain into the "Blocked Domains" sections. 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.
- From your Exchange Email panel, click on Distribution Lists.
- Select the distribution list you wish to modify from the list.
- Click on the Protection tab, then click on Disable.
This will remove Postini protection entirely from the selected distribution list.
