Change Port Webserver OpenPAAS

I changed my config to allow connections over port 80 and 443 instead of 8080 and 8443 (this is for the web-interface). When I run grunt dev, it tells me that I have a fatal EACCES error because permission is denied to listen on that port. I am also unable to send or receive any emails as the James server admin console gives me this: {“statusCode”:404,“type”:“notFound”,“message”:“GET / can not be found”,“details”:null}

Does anyone know how to fix these issues? I am using the development install I found on github.

So, you first need to fix to able to listen on these ports. This is a Ops part and you can get the answer around the internet.
