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.
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.
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:
Important: Depending on administrator settings, you may not have access to all the features described below. Contact your PureMessage administrator for more information.
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,
To access the EUWI:
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:
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:
The Blocked Messages page displays all email messages that are quarantined by PureMessage due to spam content. Using the Blocked Messages page, you can:
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.
To view a blocked message:
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.
Use the Not Spam feature to indicate that quarantined messages are not spam.
Displays messages deleted from the Blocked Messages page. Sort deleted messages based on spam Score, the email address listed in the From header, the message's Subject, or the Date the message was blocked. 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.
To undelete a message:
The Approved Senders page lists email addresses that are known to be legitimate sources of email. 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 Blocked Senders page lists email addresses that are known to distribute spam or viruses. The EUWI 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.
Use the Options page to set or modify individual PureMessage email-filtering preferences.
Use the Hold Messages option to keep messages for longer than the default quarantine period (14 days). For example, you may want to extend the hold time while you are on vacation. Specify a hold period using the day, month, and year drop-down lists. By default, you can select a date up to seven days from the current date.
Note: This feature is only available if the system administrator has enabled it. If the administrator disables this setting, the Language Preference portion of the Options page is not displayed.
Use the Language Preference option to change the language in which the EUWI and this documentation are displayed.
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.
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.
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.
