Dear Maintainer,
I accidentally copied an RSA private key to /etc/ssl/certs directory.
After that postfix was not able to start anymore and I could not find
any obvious reason why.
"systemctl status postfix" showed that it was running, however when I
checked the listening sockets, I could not find postfix.
Status was:
Active: active (exited)
It would be nice to be able to see that postfix could not start.
I figured out that /usr/lib/postfix/configure-instance.sh:84 caused the
problem...
openssl rehash exited silently with exit status 2.
Regards,
Mihaly
