157731 story Comcast Goes to Zimbra 143 Posted by ScuttleMonkey on Monday May 07, 2007 @12:11PM from the exchange-assassination dept. tenchiken writes "Zimbra, an Open Source enterprise messaging app, just scored a major win. Comcast will be moving mail services to Zimbra for all of their customers. Zimbra has been picking up steam for a while now, and appears to really be challenging Microsoft in a area that Exchange has been dominated in. Add in support for Samba Domain Controllers and Linux Authentication, Offline Access and Evolution Support and we might finally have our long desired Open Source Exchange killer."
