Hi, thanks for helping. I need to mention that I'm not a coder or any IT specialist for that matter. I'm just a user who wants to accepts emails. To my knowledge, we have Centos.
when I used this command, there was some kind of installation process and was completed.
when I ran this one, Terminal replied:
"Trying 142.251.5.27...
telnet: connect to address 142.251.5.27: Connection timed out
Trying 2a00:1450:400c:c1b::1a...
telnet: connect to address 2a00:1450:400c:c1b::1a: Network is unreachable"
What should I do here? BTW your help is highly appreciated!
