Discontinued
Not sure if 'discontinued' is quite right, but James has now officially moved in 'maintenance mode', with little or no ongoing development or support. See the readme: https://github.com/james-proxy/james#this-project-is-in-maintenance-mode.It would be helpful to highlight that here imo.
