I am beginner in Linux and Networks. My question is very weird I know, but I could not find answers on internet. Okay, so I want to send e-mail from my laptop to my gmail account. I am using Postfix client to send an email but it's not working. I am not hosting any website or server. I am simply connecting to the wi-fi network of my university. What should be my domain name then? (currently, domainname returns (none) I went to whatismyip.com and used host command host <myip> 196.40.xxx.xxx.in-addr.arpa domain name pointer abc.cs.xxx.edu. so, my FQDN is abc.cs.xxx.edu ??? I'm getting more and more confused as I come across new page on the internet. Please help me out. Thanks.
