Default Postfix/SMTP Beginner Problem

I'm able to send/receive emails locally, but not externally. All the required ports are open on my home router. Attached are my current firewall rules, main.cf, mail.log - tail end of it, and my godaddy zone file. My server was set up following

Everything went smoothly, but I just don't completely understand what I'm doing wrong with postfix and/or smtp. I'm unable to telnet outside of my LAN, and when I went here

and ran the blacklist check, two websites have me blacklisted, even though I've never had the website going until now. The SMTP check failed as well.

I added the results of lsof -i -n -P. I have some netstat runs as well, if need be. I could also install nmap and run that. It would probably be best to run all of these from a different computer, though. I'll also run them on my router. Will take a minute.
