Hi There,

We have a CentOS 7 Server that is running several KVMs of both CentOS 7 and CentOS 8.  We have a CentOS 7/Postfix KVM running as a production mail server in this environment.

This is actually a packaging problem from CentOS. The systemd service file is not configured to wait until networkign is up before it attempts to start postfix. Try the following:

Run "systemctl edit postfix.service" and insert:

[Unit]
After=network-online.target


This should tell systemd to wait until networking is up before it attempts to start postfix.
