Redmine

the pop3 email checker always produces output, even with the --silent flag sent to rake
this line is in my crontab
rake -f /var/www/redmine/Rakefile --silent redmine:email:receive_pop3 RAILS_ENV="production" host=*** username=*** password=*** delete_unprocessed=1

and it sends an email every 5 mins telling me that no email was processed

running ruby 1.8.7
rails 2.3.5
on ubuntu 10.04
