How is the network configured? Netplan? If netplan then what "renderer" is configured? systemd-networkd? Is it a local static IP configuration? Or DHCP? I have observed systemd-networkd to not wait for DHCP to complete but start services that depend upon the network before the network has been brought online. Your description of the problem matches this problematic behavior. If so then I would set a static IP address when would initialize faster than waiting for a DHCP server to respond. And since the description is for a mail server then it really should have a static IP address assignment. However I imagine that one might rely upon a DHCP address reservation to always configure the same address. > It is interesting to note the following: > > - If I "systemctl restart postfix", the restart will happen successfully. By the time you restart postfix the network has finished coming online. So of course there is no problem then. > - If I reboot the KVM, I will see the error above after the reboot The error indicates that when Postfix is started the networking is not yet available. The problem as described seems not to involve Postfix so much as the init system that is starting daemons needing the network without waiting for the network to finish initializing. Bob
