Cisco said today that it’s buying PostPath, which is a provider of e-mail and calendaring software, for about $215 million.

Cisco said privately held PostPath – which is based in Mountain View, Calif. – will enhance the existing e-mail and calendaring capabilities of its WebEx Connect collaboration platform.

With PostPath's software, Cisco said it will extend the e-mail and calendar functionality of its flexible software-as-a-service (SaaS)-based collaborative platform that includes instant messaging, voice, video, data, document management and Web 2.0 applications. This combination will enable customers to use collaboration to accelerate business processes, within and between businesses.

"The acquisition of PostPath complements our strategy to develop an integrated collaboration platform designed for how we work today and into the future, providing real productivity gains and a more satisfying user experience," said Doug Dennerline, Cisco’s senior vice president of the Collaboration Software Group.

The acquisition is subject to the standard closing conditions. Cisco anticipates that it will be completed in the first quarter of fiscal 2009.
