Administration
I am a user. Where can I get training on how to use the Message Center?
We have a simple PDF document that can be downloaded and printed for your reference on how to use the features of the message center and how to manage the spam that was captured in your quarantine. The Quick Start Document can be found HERE
How do I login? What is my username and password?
Email Cleaners will setup your account and it will be the primary email address that you normally give to people for work. After your Postini account is set up, you will receive an "Activation Message" containing login instructions with password details. For security reasons, the password will be specific to the Postini service and will be different from your regular email account password. You will also receive one email notification daily with login instructions when suspicious messages have been directed to your Postini Message Center. To login to your message center, click the following link: http://login.postini.com
Anti-Spam / Junk Email Questions
How does Postini work?
Your email passes through Postini's automated filters that detect suspected junk email and viruses. Suspicious email is directed to your personal, web-based, password-protected Message Center (it does not arrive at your regular mailbox). Think of this as a quarantine area. In your Message Center you can read the quarantined email online, delete it, or deliver (forward) it to your regular mailbox.
The Postini services are private and secure. The junk email and virus protection is an automated process. Nobody has access to your email except you. Nobody will read your email. Your email is not censored, YOU control the filter settings.
How are the Junk Email Filters different from the spam filters in my email client?
About 95% --- that's how accurate your filters can be with the Junk Email Assistant superior design. In addition, the mail filters found in email products have a number of limitations and often assume a "one size fits all" solution. You are often expected to develop your own filter rules from the limited tools provided. Further, you must still download email before the mail client can filter it, possibly wasting time and bandwidth while waiting to read mail, such as spam, that you would not want anyway.
The Junk Email Assistant filters do all email processing behind the scenes before it arrives in your inbox. This saves time and bandwidth by not forcing you to download superfluous email, such as unsolicited offers. Moreover, improvements to the filters are done without modifications to your email client or account.
Will I still receive all of my email? What does Postini do with email that has been filtered?
Postini holds any suspected junk mail or virus-infected email in your Message Center, which you can then view and delete or have delivered on to your regular email account. Delivered email will be available to you the next time you check your email. Suspected spam or junk mail messages will be held in the message center for 14 days, after which they will be deleted. You can check on the filtered messages in your Postini Message Center at any time. For instructions on logging in to your Postini Message center, see the User Login & Help section.
How do I know junk email is being filtered and not my regular (legitimate) email?
Advanced filtering technique built on heuristic rules, lists of approved and blocked senders, and databases of known junk email maintain the effectiveness of the rules system. Despite these advanced measures, some good email may get caught since the concept of junk email is subjective (one man's trash is another man's treasure). To remedy this, you can set a lenient-to-aggressive tolerance for filtering suspicious email: lenient filtering potentially lets more junk email through, but also minimizes the risk of legitimate email from getting mistakenly directed to the Message Center; conversely, aggressive filtering catches more suspicious email at the risk of mistakenly diverting normal email to the Message Center. You are notified with regular summary reports of your activity.
Does someone read personal emails?
No. All email processing is done through automated filters, in milliseconds. In the event a "suspicious" email is discovered, it will be directed to your private Message Center pending your review. If you would like to pass on a suspicious email to spam@postini.com for analysis, feel free and forward it.
Am I notified when email is quarantined as suspicious junk email?
You will receive a regular report via email of the activity in your Message Center. However, you can log in to the Message Center at any time to monitor and review detained messages.
What are Message Center filter categories?
In addition to the Bulk Mail default filter category, you can also select:
What is Filter Sensitivity?
Filter Sensitivity determines how aggressive the filters are in capturing suspect email. The settings are Lenient, Moderate, and Aggressive. Lenient will capture less suspect email, while aggressive is likely to capture more.
What is the Approved Senders list?
Entering specific email addresses or entire domains to the Approved Senders list will allow these to override your junk mail filters and allow that email to flow directly to your inbox.
What is the Blocked Senders list?
Entering specific email addresses or entire domains will prevent ALL messages from those listed will be detained in your Message Center.
What if I want to receive junk email?
You can turn the Junk Email Assistant off at anytime by simply logging in to your Message Center, and turning OFF the Junk Email toggle switch on the Junk Email page. (Other applications, such as virus scanning, can also be turned on or off in this manner.)
However, if too much legitimate email is being detained, first try setting "Filter Sensitivity" to moderate or lenient and/or uncheck any "Filter Categories" that are unwanted. It also helps to explicitly list certain email addresses to allow their messages through the filters, regardless of content. Do this by entering valid addresses in the Approved Senders field.
What happens in the event that the email processing servers' fail?
A large number of enterprise-scale servers are dedicated to processing email. However, in the event of a catastrophe, email will be passed through the system by defaulting to your email provider's regular mail servers. There will be no noticeable performance hit. Any suspect messages that were diverted to the Message Center are contained on redundant disk storage devices that are backed up.
How often is email deleted from the Message Center?
Email messages are kept in the Message Center for 14 days following the receipt of the message--this includes any messages that have been moved to your "Trash Folder". After 14 days from first receipt, any message will be deleted. Email service providers will send an email activity report on a regular basis to remind you to check your Message Center. You can also access the Message Center at any time.
What if I receive spam, what should I do with it?
If junk email reaches your inbox, you can simply delete the message or forward it to spam@postini.com. You can also visit the Message Center and add the sender's address to your "Blocked Senders" list if it appears to be a repeat offender, preventing that sender from reaching the inbox again. It might also be useful to try increasing the sensitivity level in the configuration or turn on specific filter categories.
What if legitimate email is quarantined in your Message Center?
Unfortunately, some legitimate email may be erroneously directed to your Message Center. This is due to the subjective nature of email messages and what could possibly be considered junk email. If a significant amount of valid email is being misdirected to the Message Center, You should build a list of approved senders, thereby minimizing the possibility of detaining a valid email in the future.
Also, from the Message Center, click "deliver" for any legitimate email you will be prompted to add to the sender to the "Approved Sender" list. This is the easiest way to improve your filter accuracy. You may also manually build your approved senders list by visiting your junk email settings.
Does the Junk Mail Assistant watch for obscene language and other questionable content?
The Junk Email Assistant is tuned for identifying unsolicited commercial email (UCE), otherwise known as spam or junk email. This is somewhat different than filtering specifically for content, like most email filtering. For example, a friend sends a joke containing obscenities. This originates from a known source, whereas a message of unknown origin containing obscenities that refers to a pornography site WOULD likely be directed to the Message Center.
Does the Junk Mail Assistant watch for email only written in English?
Yes, at this time English is the only language supported.
How do I set up Junk Email filters?
Is Virus Protection Assistant up-to-date on its virus definitions?
Yes. Virus Protection Assistant updates virus definitions continuously. Not only will virus scanning of malicious email viruses prove extremely valuable to you, but it also saves valuable time by scanning messages behind the scenes. You are only notified when a virus is found in a message.
How does Postini notify me that virus-infected email has been detected?
You are notified immediately via email when an infected virus is detected in an email message. From the Message Center, you can safely review the infected email text.
I am an administrator for my company. Where can I get training on how to use the Admin Console?
We have a PDF document that can be downloaded and printed for your reference on the entire range of tools inside of the admin console. The administration guide can be found HERE
How do I interpret the X-pstn-levels email headers?
Each email message handled by Postini is given a email header which describes how "spammy" the message looked to the Postini system. For example...
X-pstn-levels: (S:7.3496 R:80.5044 P:99.8514 M:95.9108 C:95.9108)
These letters and numbers can be interpreted as follows:
