Send and Receive Email

I am trying to set up Citadel on my Raspberry Pi. I can send and receive emails internally, but nothing externally. The domain name domgarofalo.net points the IP address of the Pi.

Where should I be looking to troubleshoot this?

have you set up MX records that point to your Pi? Without MX records, inbound (external) mail won't know how to get there

This free tool helps run many different parameters against a domain of your choosing (including looking up MX records).

Hold on..

If you are just sending mails outside then there is no need of MX to be setup. Check you DNS configuration and the SMTP port state. Apart from that you can check whether network traffic is open or not for that specific port because many times at the end we found "ISP" is the culprit who is not allowing the traffic on port number 25.

Apart from this "Yes" if you want to go publicly you need to setup "MX" "TXT" records as-well in order to hassle free delivery of your mails at your inbox.. :)

I do have the mx records set up and I have ports 25 and 110 open on my router. Is it the configuration settings in Citadel that are wrong?

According to all blacklists you dont have reverse DNS rercord on that IP. Ask your provider to set up reverse delegation or at least reverse host name.

Okay, I'll try that. I have my domain name pointed to the IP address that my Pi is on. My domain name is domgarofalo.net. My Citadel installation is at 65.xx.xxx.xxx:8504. I have my A record for domgarofalo.net pointed to 65.xx.xxx.xxx. I have another A record pointed to smtp.domgarofalo.net as well as an MX Record pointed to smtp.domgarofalo.net. For the folder for the subdomain, I have a redirect going to 65.xx.xxx.xxx:8504. What else am I doing wrong here?

For a inbox delivery it is recommended to follow the best practices which includes SPF,  DKIM and PTR.
