在配置 Postfix 时，我必须取消注释以下几行，然后使用service postfix restart. 重新启动时，我不断收到以下错误：
root@server-1:~# service postfix restart
* Stopping Postfix Mail Transport Agent postfix
/usr/sbin/postconf: fatal: file /etc/postfix/master.cf: line 23: bad field count
postfix/postfix-script: fatal: cannot execute /usr/sbin/postconf!
...fail!
这是其中的一部分/etc/postfix/master.cf：
smtps inet n - - - - smtpd
-o syslog_name=postfix/smtps # <<< line 23
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
出了什么问题，我该如何解决？

我正在使用以下代码：
mysql -u <redacted> -p<redacted> servermail << EOF
