I don't know courier-mta but i would go back to exim4.
Edit the files in /etc/exim4/conf.d
I added this to get exim4 to deliver to maildirs (imap)
LOCAL_DELIVERY=maildir_home

# transports
maildir_home:
  debug_print = "T: maildir_home for $local_part@$domain"
  driver = appendfile
  directory = $home/Maildir
  delivery_date_add
  envelope_to_add
  return_path_add
  mode = 0600
  mode_fail_narrower = false
  maildir_format

Before you test, stop fetchmail and try a testmessage with
exim -v email@domain.be
Blah blah blah
.
The period is to stop composing the mail and send it.
Then run a MUA that supports imap and look if it sees
the maildirs ok.
Or you can debug courier by telneting into it.
This is something i found on the net regarding debugging imap

In the following telnet example, you must provide your own password
where id_password is indicated in the login command.


telnet e-xbelize 143
