Redmine

When running the following script file I'm using:

rake -f $LAB_HOME/Rakefile redmine:email:receive_imap RAILS_ENV="production" \
  host=extranet-stme.sf.intra.laposte.fr username="Fo GDI" password="transagdi259*" \
  project=lab --trace

Nothing is handled and no messages are found neither on stdout nor productin.log file).

On stdout :

(in /tmp)
** Invoke redmine:email:receive_imap (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute redmine:email:receive_imap
spirou(redadm)$

When I submit these same mails to redmine:email:read, they are correctly handled. So I understand that the mail contents are okay.
