aapanel is mucuh great, can make hosting easy going. assumed it's not difficult to host mailserver, but ISP blocked port 25 and 110. Any solution? Thanks!
In VPS (in Cloud environment) or at home you have ports blocked?
I believe that normal ISP will block outgoing packets to port 25, they do not block incoming packets to port 25.
Please check, open a service at port 25 and check port listener
duy13 so, the only solution is to let ISP open port 25, right?
elastix or manually change the port. 25/26 110/111
