The most important points to remember about the Sophos PureMessage configuration are:

1. WJU Administrators do NOT scan email during the SPAM process. The server receives updates to the SPAM configuration from the software vendor, Sophos.
2. Any SPAM message stopped by PureMessage will only be held on the server for 1 week. After 1 week the message will be automatically deleted.

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 network, not in messages that originate within the local domain. If a message is found to have a spam probability of 50% or more, it is moved to the PureMessage Quarantine and not delivered to your Inbox.

Message Quarantine

The Blocked Messages page displays all email messages that are quarantined by PureMessage due to spam content. Using the Blocked Messages page, you can:

• view blocked messages
• release misclassified legitimate messages from the PureMessage Quarantine and deliver them to your mailbox
• delete and send messages to the Deleted Messages page
• deliver and approve a sender
• delete all messages in the list

You can sort quarantined messages based on the spam Score, the email address listed in the From header, the message's Subject, or the Date the message was delivered. Note that the date column displays the time in hours and minutes for messages blocked in the last 24 hours. Both the time and date are shown for messages blocked more than 24 hours ago.

Options

You can choose to have all of your email delivered to your Inbox. This means that PureMessage will NOT scan your email for SPAM. Select the appropriate box on the Options page and click Save.

Also, PureMessage can automatically send you a mail message that summarizes the list of blocked messages in your Quarantine. This way, you do not have to visit the Message Quarantine site. Select the appropriate box on the Options page and click Save.
