POSTINI SPAM FILTERING
Message Center User Guide
THE POSTINI MESSAGE CENTER
Postini is an email protection service that provides each user with
a Message Center where your spam and viruses are filtered and quarantined.
Your legitimate email messages are delivered to your email inbox, just
as they always have, but junk and virus-infected email is routed to
your Message Center.
Getting the most out of your Message Center
It is strongly recommended that you check your Message Center daily
at first so your filters "learn" to be more effective
and accurate. Upon regular review, remove the unwanted messages and
deliver the ones you want. You can also safely read the contents of
a virus-infected email in your Message Center without the risk of harming
your own personal system. Adjust the filters to meet your unique needs.
Regular reminders will instruct you to check your Message Center and
review quarantined email. All quarantined messages are held for 14 days
until they are automatically deleted.
LOG IN AND OVERVIEW
How do I access my Message Center?
Once your account has been activated, you will receive a "Welcome"
email directing you to your message center.
Log in to the Message Center
- Click on the Message Center link in the Welcome message. It's helpful
to bookmark the log in page.
- Enter your log in address (provided in the Welcome message).
- Enter your temporary password (provided in the Welcome message).
If you enter an incorrect password, the Forgot your Password? link will appear. Click on that link and then click the Submit button
and a new temporary password will be emailed to you.
- When you sign in using your address and password, your browser can
"remember" you by using a persistent cookie on your computer.
By selecting the checkbox on the log in screen, you can bypass the log
in each time you come back. Be sure to close the browser window
instead of logging out. Upon your return, you won't be prompted
for a password. If you use a shared computer (in a library, Internet
cafe, school, or other public area) where someone could see your personal
message center, do not select the Remember Me checkbox.
The Message Center Main Window
The Message Center has several different areas:
The Quarantine Area
If you would like to view the contents of a message in the quarantine
list (for example, if you are uncertain if an item is junk), click on
the subject, and the message content will appear.
||This message is general bulk email.
||This message contains sexually explicit
||This message contains "Get Rich Quick"
and other financially related offers.
||This message contains special offers
||This message contains racially insensitive
Remove or Deliver Email Messages
Remove Junk Email
To remove or deliver messages, check the messages and click the appropriate
button (Remove or Deliver).
When delivering a message to your inbox, you will be prompted to add
the sender to your Approved Sender List. Adding the sender will allow
them to always bypass the Junk Email filters. It is highly recommended
that you add your friends, family, colleagues, and associates in order
to improve the accuracy of your filters.
DELIVERED AND REMOVED FOLDERS
When you deliver email from the Message Center, it is immediately forwarded
to your inbox. A copy is also placed in the Delivered Folder. Messages
are permanently deleted from the Delivered Folder on a periodic basis.
To view the contents of the folder, click the Delivered link.
Once a junk email message has been deleted from the Message Center
it is placed in the Removed Folder. Messages will be permanently deleted
from the Removed Folder by the system on a periodic basis. By clicking
"Empty Trash", all messages in the Removed Folder will be
permanently deleted with no method of recovering them.
Junk Email Filters
Each messages is scored by its probability for being
junk email. Postini will compare the spam score of the message with
your personal tolerance levels for that specific category of junk email
(screenshot follows). Messages exceeding your tolerance will be quarantined
to your Message Center.
The filters can be tailored to match your personal preferences.
For example, you may wish to receive special offers, so you would set
that filter to a lenient setting, but you may not wish to receive any
get rich quick offers, so you would set that filter to a more aggressive
What do the filter levels mean?
As you increase the spam filter levels, you increase
the amount of junk email that is caught and the effectiveness of the
system. You also have a greater chance of legitimate email being quarantined
(called a "false quarantine") during the initial 'breaking
in period'. Setting filters is a trade-off — a more aggressive
setting means more junk email will be quarantined, however, it also
increases the odds of a false quarantine occurring.
The Approved Sender List allows you to designate individuals
or domains that will always bypass the filters and will automatically
be delivered to your inbox. We recommend that you add friends, family,
and associates to the Approved Sender list. This is the best method
for preventing legitimate messages from being falsely quarantined.
The Blocked Senders List allows you to designate addresses
that will always be blocked regardless of content. We do not recommend
using the Blocked Sender list to block regular spammers. Spammers continually
change and spoof their address and domain, making this approach useless.
The Blocked Sender list is to help block newsletters that are difficult
to unsubscribe from or bothersome senders.
There is only one setting for Virus Scanning, ON or OFF.
If a virus is detected, your message will be safely detained
in the Message Center and you will be immediately notified via email.
You can safely view the virus-infected message from within the Message
Center without fear of transmitting the virus to your operating system
or installed software.

owner of the address. You may submit as many alternate addresses as

FREQUENTLY ASKED QUESTIONS
- How do I know when I have messages in quarantine?
You should log in to your Message Center periodically to review your
quarantined messages, deliver any legitimate messages and remove junk
messages. You will receive an email notification on a regular basis
in your primary email inbox if any messages have been quarantined.
- How do I get technical support?
Contact your email administrator directly.
- What if I don't want my email to be filtered?
Set Junk Email Blocking to off in your Junk Email Settings page or
contact your email administrator.
- Can someone else read my email?
Postini's patent-pending email processing technology allows messages
to be processed in real-time as the packets flow through the Postini
servers, and so legitimate messages are not written to disk. This
ensures that Postini does not expose your data to hackers or potential
loss of data. Postini's filters process all email without human contact
with mail flow or individual messages. In the case of suspicious email,
the message can be broken down into sections with a hashed file name
and then directed to your private Message Center.
- Why do I need to enable cookies when logging into my Message
Cookies are only used to identify and validate users. The persistent
cookie contains the email address of the user who last logged in to
Postini. This cookie is only used when logging in. All other cookies
expire within 40 minutes or when the browser is exited. When the "Remember
my Address and Password" checkbox is checked, then the cookie
will not expire for the Message Center until the "Logout"
link is clicked.
- What happens to messages I have delivered from the Message
They are delivered directly to your inbox and a copy is placed in
the Delivered folder.
- What happens to email I delete from quarantine?
When messages are removed, they will be completely purged from the
Removed items folder approximately 2 days after removal. If you would
like the purge to be immediate, click on the "Empty Trash"
button from the Removed folder. Unless specifically removed, messages
will be quarantined for 14 days.
- Why can't I log in? What if I have trouble getting in to
my Message Center?
If you enter an incorrect password on the log in screen, the system
will display a page with a "Forgot your Password?" link. Click on
the link and then press the Submit button and a new password will
be emailed to you. If this fails, contact your email administrator
directly for assistance.
- What if I have two separate email addresses?
You should map all your email accounts to the same Message Center
to ensure spam does not get through. See the Account Settings section
of the Configuration chapter.
- Can I import my contacts or address book?
No. You can manually enter them. We suggest adding the domains, if
practical, so you do not reach the character limit for the Approved
- What if messages are quarantined that I want delivered to
my email inbox (false quarantines)?
Adjust your spam filters to a more lenient setting and add senders
to your Approved Senders list.
- What if a lot of junk email is still getting through?
The heuristic filters can block up to 95% of spam from reaching your
inbox. Unwanted messages can still get through. Follow the suggestions
below to maximize your filter effectiveness:
- Increase your settings. The more aggressive
the filter setting, the fewer spam messages will reach your inbox.
Please note that more aggressive the setting, the more often you
should visit the Message Center to confirm that legitimate messages
are not quarantined. If they are, add those senders or domains
to your Approved Sender list.
- Review your Approved Mailing List. Do you have
other email addresses forwarding to this account? Check to be
sure your email addresses are NOT on the Approved Mailing List.
