Redmine

Hi,

I'm using a cronjob to receive mails from my IMPA account,these work great but the mails are not moved to the mentioned folder, I always get following trace:

Here is my command:

/usr/bin/rake --trace -f /usr/share/redmine/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=HOST port=PORT ssl=1 username=my@mailbox.tld password=12234 move_on_success=Success move_on_failure=Failed

I have checked the typing and the location of the folders (INBOX/Success and INBOX/Failed), in Thunderbird moving Mails from one folder to the other works.
