I am configuring MyCollab and have setup the system to use the default port. What I have done is configured my public IP with a No-IP service to allow me to access my system from anywhere. So for example I have and it redirects to my IP address to connect to My Collab. I then configured my router to redirect port 80 requests internally to port 8080 and to the internal server. This all works well, without issue.

The issue I have is that the emails send with the public IP address and the port. I can live with (although prefer not to) the IP address showing as they go to internal people only. I however need to remove the port information from the email as it causes it to not work. Is this possible?
