Sounds a little tricky. For backend server, director makes sense. But for LDA, it's also suggested to deploy the LDA on the same machine with backend server? Topologically, it's very possible the machine where LDA is running is separated from one of backend server. I will run the similar tests with pure dovecot LDA, instead of ours to see the result.

Yes, the only 100% safe way is to do all simultaneous mailbox access via
the same backend server.
