You should check if there is a postfix service file for systemd: [root@server ~]# rpm -ql postfix | grep service /usr/lib/systemd/system/postfix.service If not, create one at the given path: [root@server ~]# cat /usr/lib/systemd/system/postfix.service [Unit] Description=Postfix Mail Transport Agent After=syslog.target network.target Conflicts=sendmail.service exim.service [Service] Type=forking PIDFile=/var/spool/postfix/pid/master.pid EnvironmentFile=-/etc/sysconfig/network ExecStartPre=-/usr/libexec/postfix/aliasesdb ExecStartPre=-/usr/libexec/postfix/chroot-update ExecStart=/usr/sbin/postfix start ExecReload=/usr/sbin/postfix reload ExecStop=/usr/sbin/postfix stop [Install] WantedBy=multi-user.target Then reload systemd and start the service: systemctl daemon-reload systemctl enable postfix systemctl start postfix systemctl status postfix Best regards Gerald
