is selling the e-mail serviceÂ to VMware as part of an effort to focus on the Internet services that generate most of its revenue.
Financial terms of the deal announced Tuesday weren’t disclosed.
Yahoo, based in Sunnyvale, Calif., bought Zimbra for $350 million inÂ.
Zimbra manages more than 55 million e-mail boxes for businesses, universities and Internet service providers.
The acquisition opens aÂ new product line for VMware, which sells software that enables a single computer to function like multiple machines.

The sale is expected to close by the end of March.
