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.

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, unless you remove or deliver them.

Junk Filter Settings

Each message 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 setting.

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.

Sender Lists

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.

It is important to note that the filters are on a computer is outside the Internet Montana mail server. In other words, email sent from one Internet Montana user to another Internet Montana user does not get filtered, so you do not need to put any imt.net email addresses in your approved senders list.

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.
