Version 5.4 Release Notes

Release Date: October, 2007

Improvements (5.4)

PureMessage now uses certificate validation to verify the authenticity of installations, upgrades, and all subsequent software and data updates. This offers assurance that the content you are downloading is from the Sophos website, not from a spoofed location. If you are upgrading to version 5.4 from a previous version of PureMessage, you must retrieve the latest version of the PureMessage upgrade program (pmx-setup) when prompted. Otherwise, certificate validation will not take effect. See “Installing PureMessage for UNIX 5.4” and “Upgrading to PureMessage 5.4” for more information.
You can now use the Groups Web Interface to search the mail and message logs for records of past messages. To take advantage of this functionality, the Log Search Index service must be enabled, and you must have selected the Postfix mail transfer agent during PureMessage installation. In addition, ensure that the awk and mkfifo UNIX utilities are installed on your system.

On fresh installations that use Postfix, the Log Search Index service is enabled by default. However, if you upgraded to version 5.4 from a previous version of PureMessage, you must enable the service manually (see “Managing the Log Search Index Service” in the Manager Reference for specific instructions).

When using the log search option, you select a reason (for example, "Virus") from the Reason drop-down list. Although this list contains several default reasons, you can customize this list as described in “Adding and Deleting Custom Log Search Reasons” in the Administrative Groups section of the Administrator's Reference.
An additional message log key, “pmx_action”, makes it easier to track down information for messages that are addressed to multiple recipients or that contain addresses included in PureMessage administrative groups. This portion of a message log entry begins with “pmx_action=”. See “Message Log Syntax” in the Logs and Reports section of the Administrator's Reference for details of the data contained in each pmx_action entry.
The default policy in version 5.4 differs from the policy shipped with previous versions of PureMessage. However, if you are upgrading to 5.4 from a previous version of PureMessage, your existing policy is preserved. To view the contents of the modified policy, see “Default PureMessage Policy Script” in the Policy Configuration section of the Administrator's Reference.
PureMessage has added support for the following operating systems:
- Solaris 10 for x86
- Red Hat Enterprise Linux Server 5
- SuSE Enterprise Server 10
- Debian 4
- FreeBSD 6.2
PureMessage has added support for these web browsers:
- Internet Explorer 7
- Firefox 2.0
The PureMessage User Guide been refined and enhanced for better navigation. You can access topics directly from the table of contents, or type keywords in the search box. If you prefer to view the complete documentation as a PDF, links at the bottom of the table of contents offer direct access to PDFs in US Letter or A4 format.

Resolved Issues (5.4)

Sometimes, during rotation of the PostgreSQL database log file (/opt/pmx/etc/pg_log), the database would shut down and not restart. This occurred when the database took longer than one minute to shut down. The database now stops within the alloted time. (DEF13631)
