Redmine

Hi,

I'm trying to import emails from my IMAP server.
But, all my emails are moved to fail folder.

rake redmine:email:receive_imap RAILS_ENV="production" \
    host=imap.1and1.fr port=993 ssl=1 \
    username=MY_EMAIL_ACCOUNT_ADDRESS password=MY_EMAIL_ACCOUNT_PASSWORD \
    project=MY_PROJECT_ID tracker=MY_TRACKER_NAME unknown_user=accept no_permission_check=1 \
    move_on_success=inbox/read move_on_failure=inbox/fail \
    --trace

When I tried to create an issue by email, I use the email address of my admin user.
My email contains only the description of my new issue and email subject contains the issue subject.
So my email contains: user, subject and description.

When I tried to import emails from command line, there is no error, but email is moved to fail folder.
I don't understand where is the problem.

root@s15879177:/usr/share/redmine# rake redmine:email:receive_imap RAILS_ENV="production" \
> host=imap.1and1.fr port=993 ssl=1 \
> username=MY_EMAIL_ACCOUNT_ADDRESS password=MY_EMAIL_ACCOUNT_PASSWORD \
> project=redmine tracker=anomalie unknown_user=accept no_permission_check=1 \
> move_on_success=inbox/read move_on_failure=inbox/fail \
> --trace
