Courier IMAP encodes that information in the name and location of the
file holding the message in the maildir folder.  When I list messages
in an IMAP folder the new messages move from the 'new' directory to
the 'cur' directory (in the maildir structure), and each message file
gets ":2," appended to its filename.  When I view/read a message body
the filename suffix changes from ":2," to "2,S".  The contents of the
file itself do not seem to change during either of these operations.

I would expect any other IMAP server based on maildir storage to work
much the same way.  It should be easy to verify if you can access the
server.
