PureMessage for Microsoft Exchange 2013 (PME 4.0) now available


PureMessage for Microsoft ExchangeToday sees the release of PureMessage for Microsoft Exchange (PME 4.0) to support Microsoft Exchange 2013. At this stage PME 4.0 is a separate download from the PME 3.1.3 version that supports Microsoft Exchange 2003, 2007 and 2010. We are planning to integrate both versions into a single install set soon.

PME 4.0 enhancements include whitelisting of attachments to exclude them from content filtering and auto-configuration of Active Directory settings on start-up.

Read on to learn more about this update.

What are the big differences from PME 3.1.3?

The differences in PME 4.0 are mainly due to Microsoft Exchange 2013 enhancements, rather than any changes in PureMessage for Microsoft Exchange. Microsoft Exchange Server 2013 introduces a number of new features including a single web-based administration interface, reduced server roles, and high availability improvements.

The one major change for PME 4.0 is information store scanning support. Microsoft recommended in previous releases that anti-malware vendors use their Virus Scanning API (VSAPI) to provide information store content scanning. Microsoft said it has removed this API in Microsoft Exchange 2013 because scanning of very large information stores does not scale, leading to performance and stability issues.

The retirement of the VSAPI means that PME 4.0 now provides background scanning (scanning the information store after every virus identity, or IDE, update) of Exchange private and public information stores using the Exchange Web Services API (EWS API). In following the Microsoft recommendation to scan mail in transit, PME 4.0 does not support the legacy proactive and on-access information store scanning modes.

At the time of this release, the Edge Transport server is not available in Microsoft Exchange Server 2013. However, you can continue to use your existing, or install a new, Microsoft Exchange Server 2007 or 2010 Edge Transport server in your perimeter network.
