I am trying to configure inbound email on openproject. I am using below command from the official documentation:

openproject run bundle exec rake redmine:email:receive_imap host='myimaphostdomainename' username='openprojectemailaddress' password='emailpassword' port=993 ssl=true allow_override=type,project project=openproject

Note that openproject is deployed on Ubuntu server in /opt/openproject and that's why I named the project parameter in the command as openproject (project=openproject). However this did not work and gives below error message. Note that the email account is normally working very well.

Then I also tried to remove allow_override and project attributes and rerun the command but still it fails. Below is the command:

openproject run bundle exec rake redmine:email:receive_imap host='myimaphostdomainename' username='openprojectemailaddress' password='emailpassword' port=993 ssl=true

Someone who knows what is going on can help me please. Your help is appreciated.

Best regards,

Sorry, below is the error message that come when running both commands:

*  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *

    *   OpenProject requires UTF-8 encoding set on MySQL < 5.7              *
        and UTF-8mb4 beyond that. Please ensure having set

It is giving authentication failure yet the email account works very well.
