[Dovecot] gmail pop3 fetcher sets my emails as read

[Julien Buratto]

Hello,

I'm testing gmail to fetch my emails via POP3 and I've noticed that on
the server where I run dovecot, the emails that gmail take, are marked
as read when I imap my emails with my thunderbird.

As I've noticed that this is not true for the email accounts on
another mail environment, I was wondering if anyone of you could
sugged where I could change the behaviour.

My configuration is:
# 1.1.8: /etc/dovecot.conf
# OS: Linux 2.6.9-67.0.4.EL i686 CentOS release 4.7 (Final)
log_path: /var/log/maillog
info_log_path: /var/log/maillog
protocols: imap pop3 pop3s
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable(default): /usr/libexec/dovecot/imap-login
login_executable(imap): /usr/libexec/dovecot/imap-login
login_executable(pop3): /usr/libexec/dovecot/pop3-login
mail_location: mbox:~/mail/:INBOX=mbox
mail_executable(default): /usr/libexec/dovecot/imap
mail_executable(imap): /usr/libexec/dovecot/imap
mail_executable(pop3): /usr/libexec/dovecot/pop3
mail_plugin_dir(default): /usr/lib/dovecot/imap
mail_plugin_dir(imap): /usr/lib/dovecot/imap
mail_plugin_dir(pop3): /usr/lib/dovecot/pop3
auth default:
  cache_size: 1024
  verbose: yes
  passdb:
    driver: pam
    args: session=yes cache_key=%u%s dovecot
  userdb:
    driver: passwd

Thank you for helping
