I was trying MailCow Installation from Portainer, But I was much time Failed.
Any can guide me? How to proper way deploy MailCow Stack on Portainer? And How to proper way to configuration?
Since you need to generate mailcow.conf using a script + update mailcow you can’t just deploy mailcow using portainer. Login to your server via SSH and follow the installation docs: https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_install/
