How do I change smtp port? Or add additional one?
I follwed the guide for ISPConfig 18.104.22.168 on Debian 6.0.
I am finished with the installation but i need to change or add the smtp port.
My isp is blocking 25 so maybe 2525 might be an option? Should I add this as an alternative port or modify 25?
..and finally, how do I do this?
