Sorry we didn't respond to your earlier message. This is possible, but it is unsafe to be fully multi-master - each user should only be logging in at one of the locations. And full 3 location multi-master is not well tested. There are caveats. We ran like that at FastMail for a while - but there were edge cases where some of our "fixup" tools could confuse it and cause the mailbox to fill up with multiple copies of the mailbox, or a delete to get replicated the wrong way because a mailbox hadn't been created yet. In short - you need to know what you're doing and be careful right now, but it is something we plan to support more robustly.
