[Dovecot] POP3/IMAP newbie question

[Lars Stavholm]

Is it possible to serve both POP3 and IMAP for the same
user from the same mailbox format, e.g. the maildir format?

If so, how should I configure in dovecot.conf?

At the moment I have (dovecot -n):
# 1.1.beta2: /etc/dovecot/dovecot.conf
base_dir: /var/run/dovecot/
protocols: imap imaps pop3 pop3s
ssl_disable: yes
disable_plaintext_auth: no
login_dir: /var/run/dovecot//login

  username_format: %n
  passdb:
    driver: pam
    args: blocking=yes dovecot
  userdb:
    driver: passwd
    args: blocking=yes
  socket:
    type: listen
    master:
      path: /var/run/dovecot/auth-master
      mode: 384
plugin:
  quota: fs:storage=102400
  trash: /etc/dovecot/trash.conf
  sieve: ~/.dovecot.sieve
  dspam: /usr/sbin/dspam:Spam:nosignature:Trash:users
  autocreate: Spam

I.e., I use the same mail_location for both POP3 and IMAP.
However, mails are delivered to ~/Mail/inbox and seems to
be invisible to both my IMAP and POP3 client (Thunderbird).

Any input appreciated
