How to recieve emails with Redmine in Docker?

Added by Alexander Pedersen 12 months ago

It seems the documentation is not updated for Docker: http://www.redmine.org/projects/redmine/wiki/RedmineReceivingEmails

I want to "Forwarding emails from your email server" for Redmine running in Docker..
But how do I access rdm-mailhandler.rb when it's in the Docker image?
