That would result in doubling the bandwidth on the inside server connectionIs the cost of bandwidth to your inside server really so expensive as to justify the expense of complicated development, hosting an offsite server with that much bandwidth, and maintaining a remote system? It really sounds like you are overengineering the problem.
since it would be dealing with the mail first coming in to the MX, then
being replicated back out to the other server. By delivering outside mail
to the outside server first, the only bandwidth usage is replicating to
the inside server (reverse the scenario for mail originating inside).
No, the time a flag was changed isn't kept. In fact for seen flags which are cached in memory while a mailbox is open, only a single bit is kept.If there was a way to track when the flags got changed. I feel it's OK to trust the clocks on the servers, and simply decide which flag state prevails based on which has the later timestamp. But I bet that metadata isn't in the current mailstore design.
