I'm in the early stages of evaluating Zimbra to replace Communigate Pro (2,000 accounts). Our growing Mac contingency is demanding a better solution to handle shared calendars, meeting scheduling, etc.
The CGP mail server has been running on an Xserve for years with no performance or hardware/software problems. From a hardware administration standpoint, we are most comfortable in an OSX (workstation or server) environment, and would like to keep it that way.
1) Will ZCS Open Source Edition run well in an OSX environment?
2) I think I read that attachments aren't indexed/searchable if the server is running on an OSX machine. Is that true?
