Can't send or Receive Emails
Hi,
I can't send or receive emails when I changed my Linux server 's IP address to another. However, I can receive emails if they were sent from my domain.
Anybody has any idea whether I need to reconfigure my Linux server? It was originally working fine until I move the server into my firewall with a new IP.
Need help on what I can do, check and reconfigure. I'm new to Linux, so I need quite detailed help. Thanks! I'm using Redhat 8.0 Pro for this server.
