Microsoft Exchange has long dominated the email server market. Until recently it was the only practical choice for IT administrators who didn't want to bother with the plug-ins or connectors needed to make non-Microsoft servers work with Outlook and other key email and collaboration technologies.

It also forced them to put up with the significant drawbacks associated with Exchange: --High cost --Outdated database technology --Limited support for virtualization --Inflexible server management environment --Difficult migration path --Limited support forWeb 2.0 collaboration tools Now a new option, PostPath Server, overcomes all those limitations and delivers much more. For the first time, organizations that are considering implementing or upgrading an Exchange server have an alternative.
