Zimbra! founder! quits! Yahoo!

As another exec reportedly returns to MS

The founder of open source email Silicon Valley startup Zimbra, which was bought by Yahoo! in September 2007, is leaving the internet firm.

Satish Dharmaraj will depart from Yahoo! in March, less than two years after his San Mateo, California-based company was acquired for roughly $350m. He will be replaced by Jim Morrisroe who takes on the role of Zimbra veep, Yahoo! said.

“He leaves behind a dedicated team who will continue to deliver open source, collaborative messaging software, and expand into new markets," said Yahoo! in a statement. "Satish's contributions to Zimbra and Yahoo have been invaluable and we look forward to his continued support of the Zimbra project."

Meanwhile, All Things Digital’s Kara Swisher, who first reported yesterday that Dharmaraj was set to walk, reckons that one of Yahoo!’s top marketing flacks, Eric Hadley, is also expected to quit the firm in favour of a new job at Microsoft’s MSN online service.

Swisher cites several sources, but neither Yahoo! nor Microsoft have issued official statements yet.

Hadley only joined Yahoo! in November last year, after previously running the sales and marketing team at Heavy.com. Prior to that he held a general manager job at Microsoft for its digital advertising solution team including MSN and Live.com.

Just last week Yahoo! wheeled out new CEO Carol Bartz, who replaced Jerry Yang. ®
