Hi everyone
I need to receive notification email from Qnap NAS Customer.
But on my Server Mail Log i receive this error:
I think is related for tls problem, but on nas side with this command seems tls 1.2 is supported:
But on nas if try to send test email i get error.
in the meantime i need to receive this email so i add the public ip of the customer in Relay Host on the server mail, but doesn’t work, if i check the connection with telnet the port 25 seems to be closed:
But if i do this command on the terminal port 25 seems to be open:
Why telnet doesnt’ connect?
