So let me make certain that I understand what > you're saying. You had two dbmail-imapd/dbmail-pop3d servers running in > possibly different locations accessing the same database, correct? Yes, this works just fine. The physical/network distance between the database server and the dbmail server is only a matter of bandwidth and latency fetching the data out. It doesn't affect operation at all. > Did these > servers have any caching abilities?

Do they have separate workstation? Let's say you have a laptop and a desktop computer, and you are running a desktop email client on each one. Those two email clients will have to keep synchronized with the server. Two servers does not help you in any way. > I'm also wondering how dbmail works when using two replicated DBs > as well.

This works very well. In fact there's no significant difference in this scenario vs. running several instances of dbmail-imapd on the same machine.
