无法使用PostFix Mail Server发送电子邮件

Question

尽管SMTP端口25处于活动和侦听状态，但我仍无法以root@TechX.com的身份从Linux服务器（3.10.0-514.10.2.el7.x86_64＃1 SMP）发送电子邮件。

[root@TechX ~]# hostname
TechX

PostFix版本为：

postconf -d | grep mail_version
mail_version = 2.10.1
milter_macro_v = $mail_name $mail_version

我检查了邮件日志（/ var / log / maillog），发现以下错误。

我有一个类似的问题，可以通过取消注释/etc/postfix/master.cf文件中的以下行来解决...

smtps  inet  n  -  -  -  -  smtpd 

我还尝试整理所有在配置了Gmail服务器的RHEL7上成功设置后缀服务器所需的步骤。 您可以快速浏览这些步骤，并找出是否错过了任何步骤。
