Installment issue with ports

Hey I just installed Discourse and I use a cpanel email setup everything not gotton the email so I did the doctor command and said port issue 465 failed and then tried 857 failed again?? I don’t understand im on
18.04 Ubuntu and I did the ufw ports and I’m just so lost. (PS is this the right Category?)


I may be wrong, but as far as I can see from my own installation, Discourse is looking for/using Port 25. Here’s my setup:

Delivery Method
address mx-out
port 25
authentication plain
enable_starttls_auto false
