Viktor,
In this piece of code, why write to a .tmp file then immediately rename it without any prior processing ? > # umask 077 > # openssl pkcs12 -nodes -in /some/where/keypair.pfx \ > -out /etc/postfix/certkey.pem.tmp > # mv /etc/postfix/certkey.pem.tmp /etc/postfix/certkey.pem > # postconf -e "smtpd_tls_cert_file = /etc/postfix/certkey.pem" -- Yassine
