Q. How does your junk email and virus filtering work?
A. Whenever someone sends email to your email address it passes through Postini's servers first. Postini's anti-virus and anti-junk filtering software checks the email for potentially undesirable content and virus-infected messages. Any messages identified as junk email or virus-infected email are quarantined by Postini in your personal Postini Message Center.

Q. Does this mean that I have to go to Postini to read my email now?
A. No. You visit your Postini Message Center to adjust your filtering preferences and to check for legitimate email which has been quarantined by Postini and deliver it to your account. Once you have your Postini filtering preferences customized to meet your needs, most if not all of your legitimate email will be delivered through to your email account normally.

Q. How much does it cost?
A. The junk email and virus filtering service is available to clients with their own domain hosted by London Webmasters for $1/address/month. Please fill out the Postini Request Form if you would like to set up this service for your own domain.

Q. How do I use the service?
A. Go to http://login.postini.com to configure your filtering preferences at Postini. You will be presented with a form requesting you to fill in your log in address and password in order to login to your Message Center.

Enter your email address in the Log in Address field and your Postini password in the Password field. (We will ask you to choose a password for your Postini account when you request set up of the service.) For security reasons, your password will appear as asterisks (*) on the screen.

Click on the green LOG IN button. This will take you to your personal Message Center. If Postini has not quarantined any email in your Message Center you will see the message "Your Message Center is empty" however, you will still be able to modify your filtering preferences using the links on the control panel which appears at the top of your Message Center.

First, click on the link marked "Junk Email Settings". This will take you to a screen with options for setting your junk email filtering preferences.

Immediately underneath the heading "Junk Email Blocking" you will find two buttons marked "ON" and "OFF". Junk email filtering is turned on by default but, if you do not wish Postini to apply any of its junk email filters to mail sent to your account, you can turn off this service by clicking on the OFF button. (If you change your mind later, you can come back and select the ON button.)

If you do wish to have junk email filtered out of your account, leave the ON button selected and fill out the section below marked "Spam Filters".

Select the level of filtering you would like applied to your email for each of the categories listed by selecting one radio button beside each filter. The "Bulk Email" filter is automatically turned on if you have junk email filtering turned on.

Click on the button marked "Save Changes" to save your filter categories choices.

The next filtering options are the "Sender Lists".

In the "Blocked Senders" section you can identify email addresses or even entire domains from which you do not wish to receive any email. All messages from these senders will be filtered out by Postini, regardless of content. This is a useful feature for blocking messages from senders who repeatedly send you unwanted email, including mailing lists which you no longer desire but from which you are unable to unsubscribe.

You will need to click on the "Save to List" button for each address or domain you wish to add to the "Blocked Senders" list.

In the "Approved Senders" section you can add the addresses of any senders whose messages you want to have always delivered to you, regardless of whether or not the content of these messages would otherwise be snagged by the filter categories and filter sensitivity you have selected for your account. Add friends, family and co-workers whose messages you want to make sure always reach you without delay. You may also want to add any mailing lists to which you belong. (Since mailing lists are by definition bulk mailings, these have a higher probability than personal email correspondence of being identified by Postini's filters as junk email. Adding any mailing lists which you do want to receive to your Approved Senders list will prevent these messages from being quarantined by Postini.)

To add a mailing list to your Approved Senders list, you need to first look at the header of an email message from the list. If the list's address appears in the "From" field in the email header, you can add it to the regular Approved Senders list. If, however, the list's email address does not appear in the "From" field but does appear in the "To" field, click on the "Yes" button beside the question "Are you trying to approve an email mailing list or newsgroup?"

Add any mailing lists whose list address appears in the "To" field of messages from the list to the Approved Mailing Lists list. You have now finished setting your preferences for junk email filtering.

Click on the link marked "Virus Settings" on the control panel if you would like to turn virus protection on or off.

Virus protection is automatically turned on when your mail filtering services are activated, and we recommend that you leave it on for your own protection. If, however, you wish to disable virus protection, this is the place from which to do that.

Once you have finished adjusting your Postini settings, click on the link marked "Log Out". This is especially important if you share your computer with others or use a publicly accessible computer such as one in a library or Internet Café as logging out of your Postini Message Center will prevent the next person to use the same computer from accessing your mail filtering preferences and any emails which have been quarantined in your Message Center.

Q. What happens if Postini quarantines email which I want delivered to my account?
A. You can always check the messages which Postini has quarantined from your account by logging into your Message Center. If there are quarantined messages there, you will see a screen similar to this one:

You can view the content of any of the messages quarantined in your Message Center without downloading it to your own computer. This means that you can even read the content of virus infected emails safely, without risk of damage to your computer. To read an email in your Message Center, simply click on the link in the Subject column of the desired email.

If you identify any emails in your message center which you would like delivered to your account, select these messages by clicking on the check box to the left of the messages which you want.

Then click on "Deliver". Postini will forward the selected messages to your LWEB account and give you the option of adding the senders of these messages to your Approved Senders list.

Select any senders who you want to add to your Approved Senders list. Leave unselected the ones which you do not want to add to this list. Then click on "Continue". This will take you back to your Message Center. The messages which you have delivered to your account have now been removed from the Message Center, leaving only the unwanted email here.

You can quickly select every message on this screen by clicking the check box in the header row or by clicking on the link marked "Select All".

Then click the "Remove" button to remove all of these messages from your Message Center.

If Postini is quarantining a lot of messages which you want delivered to your account, you may want to adjust your email filtering settings, either by changing to a more lenient Filter Sensitivity or by unselecting the Filter Category which is being used to trap the bulk of the messages which you want delivered to you.

Q. I accidentally deleted a message which I want delivered to me. Can I still retrieve it?
A. Yes. When you delete messages from your Postini Message Center they are not removed from Postini's servers but simply moved into your Postini Trash. Click on the link in your Message Center marked "Removed" to view these messages and select the ones for delivery which you would like forwarded on to your account.

Q. How long do quarantined messages remain on Postini's servers?
A. 7 days. One week after an email is quarantined by Postini it will be deleted, regardless of whether or not you have viewed the message. Therefore, if you are concerned that Postini may be quarantining email which you want to see, you need to visit your message center at least once every 7 days to ensure that no wanted messages are lost.

Q. How do I know if Postini has quarantined any of my email?
A. If Postini has quarantined any of your email suspected of being junk email, you will receive a message once a week informing you that the email is in your message center. If Postini quarantines any of your email because it is infected with a virus, you will be notified via email immediately of this quarantine.

Q. I'm still receiving SPAM in my account. What can I do?
A. Postini cannot guarantee that it's software will catch every piece of unwanted email. You can, however, increase the chance that unwanted email will be quarantined by Postini by choosing a more aggressive Filter Sensitivity, selecting more Filter Categories and adding the addresses of repeat offenders to your Blocked Senders list.

If you still receive unsolicited bulk email which gets past Postini's filters, you can forward any of these messages to spam@postini.com. This will allow Postini to analyze the unwanted email and thereby improve its junk email filtering in the future.

Q. I'm happy with the level of email filtering which Postini is performing on my account. Do I still need to check my Message Center whenever email is quarantined there?
A. If you are confident that Postini is not quarantining any messages which you want to see then, no, you do not need to keep checking your Message Center. Messages quarantined by Postini will be purged from the Postini servers after 7 days, regardless of whether or not you have been into your Message Center to manage your account. Please be certain that Postini is not trapping any important messages before you abandon checking your Message Center, because, once Postini purges the messages, they are gone, and there is no way to retrieve them.

Q. I have multiple email addresses. Do I need to check them all separately at Postini?
A. No. You can have all of your email addresses mapped into one Message Center at Postini. You would then only need to check one Message Center and would receive all notifications of quarantined email to one address. Any messages which you chose to have delivered on to you would be delivered to the address to which they were originally addressed. You will be given the opportunity to detail how you would like this address mapping feature to be set up when you fill out the Postini Request Form.

Q. Why do I need to enable cookies to login to my Postini Message Center?
A. When you login to your Postini Message Center, Postini sets a cookie which allows its servers to identify you as a unique user and prepare web pages that reflect your personalized applications. Some information, such as your login email address, is packaged into a cookie and sent to your web browser which stores it for later use so that the next time you log in you will only need to enter your password.
