Managing Mail with the End User Web Interface

What Is PureMessage?

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

This document describes how to manage email that has been processed by PureMessage. Mail management is done through a specially designed web page (the End User Web Interface). Except for the section on quarantine digests, which are not enabled by default, the descriptions that follow assume the default PureMessage configuration.

How Does PureMessage Identify Spam?

PureMessage contains numerous spam tests that analyze individual characteristics of each message. Every test 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 PureMessage determines that a message is spam, the message is copied to the quarantine. By default, PureMessage also delivers the message, altering the message's subject heading to show its spam probability. It also adds an "X-PerlMx-Spam" header to the message.

PureMessage End User Web Interface

The End User Web Interface (EUWI) gives you access to some of the PureMessage email-filtering features. You can view and manage messages that are quarantined (blocked) by PureMessage, manage user-specific sender lists, and configure various email-filtering options.

The EUWI is comprised of the following components:

• Navigation Menu: The menu located on the left side of the page.
• Main Page: The current page accessed through the navigation menu. Links to additional pages include: Blocked Messages, Deleted Messages, Approved Senders, Blocked Senders, and Options.
• Email Message Viewer: A viewer that opens when a message's "Subject" link is clicked.

Important: Depending on administrator settings, you may not have access to all the features described below. Contact your PureMessage administrator for more information.

Accessing the End User Web Interface

Access the End User Web Interface (EUWI) via the web link sent by your system administrator. A PureMessage administrator can give you access to the EUWI by either emailing you the access information or having you request a password through the EUWI. Alternatively, the administrator may add a link in quarantine digests to the EUWI.

Notification from the Administrator

Usually, the PureMessage administrator sends you an email message containing your EUWI login and password. This message also contains a web link to the EUWI (for example, https://computer.example.com:28443). To access the EUWI:

1. Click the web link in the email message. The EUWI login page is displayed.
2. Enter the login and password provided in the email message.
3. Click Login. You are logged in to the EUWI and the Blocked Messages page is displayed.

Requesting a Password

Before you request a password, the PureMessage administrator must send you an email message containing the web link to the EUWI (for example, https://computer.example.com:28443). After obtaining this link, proceed as follows:

1. Enter the link in a web browser (or click the link if it is in an email message). The EUWI login page is displayed.
2. Click "here". The Send Authorization page is displayed.
3. Enter your company email address.
4. Click Send Authorization. Your EUWI password is sent to the email address entered.

If you send multiple authorization requests, only the latest request grants you access to the EUWI.

When you receive an email message from the PureMessage administrator:

1. Open the email message.
2. Click the web link in the email message. The EUWI login page is displayed.
3. Enter the login and password provided in the email message.
4. Click Login. You are logged in to the EUWI and the Blocked Messages page is displayed.

Blocked Messages

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

• deliver and approve a sender
• delete all messages in the list
• designate that a message is not spam

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.

2. Click Save. The EUWI and the accompanying documentation are displayed in the specified language.

Setting Rules in Your Email Client Software

In the default policy configuration, PureMessage delivers all mail regardless of the spam probability. However, it modifies the subject line of messages that are determined to be spam. Additionally, email client programs can be configured to use rules (also known as filters) to handle messages based on this message characteristic. See the documentation that accompanies your email program for instructions about creating this type of rule.

Quarantine Digests

When PureMessage detects that a message contains spam, the message is stored in the PureMessage quarantine instead of being delivered. Quarantine digests are email messages generated by PureMessage that contain a list of these quarantined messages.

Quarantine digests display the quarantine message ID number, the spam probability percentage, the message's "From" address, and the message's "Subject". To release a single message from the quarantine, click on the ID number. This generates an email to PureMessage; the message is automatically released. To release all listed messages from the quarantine, reply to the message.

Exempting Digests from Client Software Rules

Some email software (such as Microsoft Outlook) have configurable message-handling rules. Often, you can set your email program exempt quarantine digests from these rules.

For example, when you enable a junk email filter or adult content filter in Microsoft Outlook, a list rule is automatically created that exempts specific addresses from these filters. See the documentation that accompanies your email program for details.
