What is PureMessage?

PureMessage is a mail-filtering program. All incoming and outgoing email messages pass through PureMessage. The PureMessage filter looks for certain message characteristics and performs actions on the message when these characteristics are found.

How Does PureMessage Identify Spam?

PureMessage contains several hundred spam tests that analyze individual characteristics of each message. Each of these tests has a numerical weight. When a message is analyzed by PureMessage, the weights from all the spam tests that matched the message are added up and converted to a spam score that expresses the message's "spam probability".

By default, PureMessage only checks for spam in messages that originate from outside the NSU network, not in messages that originate within the NSU domain. If a message is found to have a spam probability of 80% or more, it is automatically sent to the PureMessage Quarantine. If a message is found to have a spam probability of 50%-79%, PureMessage delivers these messages to your regular e-mail Inbox, but alters the message's subject heading to show its spam probability. The modifications can be used to configure filters in your email program.

You may view a message that you're unsure of by clicking it's 'Subject' in PureMessage. It will display a text-only copy of the message so no harmful attachments will be released. See below for a sample.

Below are some examples:

Blocked Messages

The Blocked Messages page displays all email messages that are quarantined by PureMessage due to spam content.

blocked messages list

Use the Deliver Message feature to release legitimate messages from the PureMessage Quarantine and deliver them to your mailbox.

Use the Delete Message feature to remove messages from the Blocked Messages page and send them to the Deleted Messages page.

Use the Deliver and Approve Sender feature to send the selected message(s) to your mailbox and add the sender(s) of those messages to your Approved Senders list.

Use the Delete All feature to remove all messages from the Blocked Messages page and send them to the Deleted Messages page.

add blocked senders

The Blocked Senders page lists email addresses that are designated by the user. The End User Web Interface can be configured to block messages originating from addresses in this list. Use the Blocked Senders feature to add or delete senders from the Blocked Senders list.

add approved senders

The Approved Senders page lists email addresses that are known to be legitimate sources of email as designated by the user. By default, PureMessage delivers email from approved senders and hosts without scanning it for spam. Use the Approved Senders feature to add or delete senders from the Approved Senders list.

The Options page allows the user to specify NOT to receive the Quarantine Digest by de-selecting the Notify me... feature.
You may 'opt out' of spam filtering completely by selecting the Disable all... feature.

The Quarantine Digest will be emailed to you semi-weekly for you to review exactly what is being filtered.

If a message is found to have a spam probability of 80% or more, it is automatically sent to the PureMessage Quarantine. If a message is found to have a spam probability of 50%-79%, PureMessage delivers these messages to your regular e-mail Inbox, but alters the message's subject heading to show its spam probability.

*Note: All items left on your Blocked Messages page for four weeks will be automatically, permanently deleted.
