Cisco is to buy PostPath, a maker of email and calendaring software, for US$215 million (NZ$308 million).
PostPath makes PostPath Server, an email and collaboration server it touts as a Linux-based replacement or supplement to Microsoft Exchange.
Cisco plans to put the server in the cloud and sell an email and calendaring service to its customers. The PostPath capability will become part of Cisco's Web Ex Connect collaboration platform.
PostPath allows interoperation between Microsoft Outlook, Exchange, Active Directory, ActiveSynch and BlackBerry Enterprise Server, among other applications, without middleware.
Cisco expects to close the deal by the end of October and add PostPath's 67 employees to its Collaboration Software Group.
