Smtp NOQUEUE:reject:RCPT from localhost[：：1]：554 5.7.1断开与localhost的连接

我正在尝试使用postfix和rails从centos发送邮件，但我收到的错误如下：

Nov 16 18:14:15 li664-186 postfix/smtpd[5477]: connect from localhost[::1]
Nov 16 18:14:15 li664-186 postfix/smtpd[5477]: NOQUEUE: reject: RCPT from localhost[::1]: 554 5.7.1 <test@gmail.com>: Relay access denied; from=<admin@my-domain.com> to=<test@gmail.com> proto=ESMTP helo=<localhost.localdomain>
Nov 16 18:14:15 li664-186 postfix/smtpd[5477]: disconnect from localhost[::1]

我已经从main.cf文件中删除了所有注释行。是否必须配置任何其他文件才能从我的服务器发送邮件** 请输出

---

mynetworks参数可能不包括IPv6 localhost:：1

而不是手动编辑main.cf内容，请发布postconf-n的输出，以显示Postfix看到的实际设置。@设置时让我知道mynetwok条目？
