Most likely one of your clients sets them unread for some reason. Have
you tried shutting down all your IMAP clients and then using only e.g.
Squirrelmail for a while?

Enabling http://wiki.dovecot.org/Plugins/MailLog and looking at the logs
might show something useful too.

Like Willie said, it's part of the filename. You could also check if the
file's ctime changes unexpectedly (i.e. it changes when filename changes
= when flags change).
