Email Interface: a way to modify the email submission/send port
Mostly of the companies that rent Cloud VM's does not allow outbound connections on ports 25, 465, and 587. By default, these outbound SMTP ports are blocked because of the large amount of abuse these ports are susceptible to. For most of us using ISPconfig it becomes a dead end. And it also becomes an adventure get a way to surround this problem without mess up ISPConfig. It would be nice to have a way to modify the email submission/send port on the interface. Maybe change those locked ports to eg: tcp: 2525
