I have setup an email server which stands behind a firewall. Internally we are able to sent and receive email. I fact we can send email anywhere. The problem lies with the incoming email --- none.
I have checked the following, 1. Allowed port 110/tcp and 25/tcp through the firewall. From outside the firewall you can telnet to the server and it responds. 2. I'm fairly sure DNS is working but I have the FEATURE( accept_ unresolved_domains) turned on ( not my favorite option ). I have attached part of the maillog. The system is Redhat 8. Its probably something stupid I am doing. Any help appreciated, Jeff
