Redmine

Hello,

I have been trying to get the mail to issue feature to work for a few hours now and progress is very slow.
I am using the following command:
rake redmine:email:receive_imap unknown_user=accept no_permission_check=1 RAILS_ENV="production" host=imap.gmail.com port=993 username=xxx password=xxx ssl=1 --trace

I also tried dig/nslookup with the host and it works fine

• Invoke redmine:email:receive_imap (first_time)
• Invoke environment (first_time)
• Execute environment
• Execute redmine:email:receive_imap
