Postfix无法接收电子邮件

我正在尝试按照本指南在Ubuntu 12.04中设置postfix和dovecot的邮件服务器。 似乎所有的工作正确，当我尝试这个echo test | mail [email protected] echo test | mail [email protected]一切按预期运作。 但是，当我尝试从我的Gmail帐户发送邮件到服务器，我得到这个错误

 Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain example.org by aspmx.l.google.com. [2607:f8b0:4001:c05::1a]. The error that the other server returned was: 550-5.1.1 The email account that you tried to reach does not exist. Please try 550-5.1.1 double-checking the recipient's email address for typos or 550-5.1.1 unnecessary spaces.

我试图用这个testing邮件服务器，我得到了1个错误，因为我的HTTPS证书是无效的，7个警告因为我的自定义SMTP横幅和缺lessSPFlogging。 关于如何更改我的HTTPS证书的任何想法，如果它有与Gmail的问题？

我也尝试从这里在线发送邮件，我得到了这个结果：

这是我的main.cf文件：

• 后缀或sendmail监控
• 2个电子邮件服务器和一个静态IP
• 如何防止用户发送邮件为其他人？
• Postfix电子邮件追踪，现在在哪里
• Postfix本地主机服务器发送垃圾邮件本身
