Here you did, so it was accepted. What did you see in /var/log/mail when this happened?
But my subnet is not in the 192.168.1.0/24 range. I tried setting it
What is your range then? You replaced it with xxx.xxx in the paste from the telnet session, but that is fundamentally useless, as no one would be able to connect to your private IPs anyway, even if you published them all. You can hide public IPs if you want (but if it's a public mail server, you have to publish it at some point) but private IPs don't have to be protected
The actual hostname of this box is not FQDN, but something like linux.local
That shouldn't be used. Ever. .local isn't a valid domain, it's reserved for zeroconf stuff. But tell us what it says in /var/log/mail when you try to send a mail. Usually postfix is very good at specifying what the problem is
