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.
I ran some more scans. Two were intensive zenmap scans from another host to my server and gateway. The other is a nmap scan through a proxy to my IP.
I did a scan from http://mxtoolbox.com and the results are much different.
25 smtp Thread was being aborted.
80 http Thread was being aborted.
443 https No connection could be made because the target machine actively refused it xx.xx.xx.xx:443
So perhaps it's a firewall issue. I'll try opening those up and see what happens.
Think I Got It Working
