When I am trying to install NAgiosXI2024 on new RHEL 9 VM, I got the following error

What is the output from journalctl -xeu postfix.service?

Coming back to this, what happens if you run /usr/sbin/postfix start in a shell prompt?

# /usr/sbin/postfix start
postfix: fatal: parameter inet_interfaces: no local interface found for ::1

schadalawada,

I believe that error indicates the postfix service can't find an interface for the IP (in this case the loopback interface) it's configured to listen on. It might be worth looking into the postfix config, found at: . I can't speak to the security of this solution, but you may be able to change:
To:
To see if that will get you past the error. However, if it's a brand new server you haven't changed any configs on it seems unlikely that the config file would be malformed.
