No, they shouldn't. The maildir filename must be globally unique. Otherwise it doesn't matter what it is. Just keep them as they are.

The main problem with rsync is going to be if two servers have the same filename, but one has renamed its flags. So there are two identical base filenames but with different flags. Then Dovecot will log a warning about duplicate message and rename one of the files.
