Bug#1051161: postfix: Postfix does not start with default configuration

[Henrik Stoerner]

Package: postfix
Version: 3.7.6-0+deb12u2
Severity: important

Dear Maintainer,

On a fresh Debian 12 Bookworm installation, the Postfix package was installed and configured as "Internet site".

The service does not start.

"systemctl start postfix" shows as "started (exited)".
journalctl for the service just says that "A start job for unit postfix.service has finished successfully." but no processes are running.

It is possible to start Postfix with the command "postfix start", then it runs as expected. But I would expect the systemd configuration to do this.


Regards,
Henrik Stoerner
