I upgraded my server from Debian 10 to 11 and everything appears to be working correctly. I kept all the old config files during the upgrade.

When I run sudo systemctl status postfix, Postfix is showing as active (exited). No errors that I could find and the config file is good. Should I be worried about the 'exited' status?

All the other services are listed as active (running).
