Postfix：收件人地址被其他域区域拒绝

我已经成功安装了具有虚拟域和 TLS 支持的 Postfix/Dovecot，如本文所述 - https://geekpeek.net/postfix-with-dovecot/...

但面临问题。我只能向我的域区域中的人员发送电子邮件（blabla例如）。这意味着我可以从 发送电子邮件[email protected]至[email protected]。但是当我尝试从我的谷歌帐户发送电子邮件到此地址时，我收到以下错误：

postfix/smtpd[19211]: connect from mail-wi0-f172.google.com[209.85.212.172]
Sep 10 18:23:17 amazon-ws.fs.local postfix/smtpd[19211]: NOQUEUE: reject: RCPT from mail-wi0-f172.google.com[209.85.212.172]: 554 5.7.1 <[email protected]>: Recipient address rejected: Access denied; from=<{myaccount}@gmail.com> to=<[email protected]> proto=ESMTP helo=<mail-wi0-f172.google.com>
Sep 10 18:23:17 amazon-ws.fs.local postfix/smtpd[19211]: disconnect from mail-wi0-f172.google.com[209.85.212.172]

收件人地址被拒绝：访问被拒绝；

我所能理解的是我的 postfix 服务器拒绝了这封邮件，但不明白为什么。 Postfix 配置（main.cf）附如下：

操作系统：RHEL7.1、Postfix 版本 2.10.1

哪里有问题？

答案1

master.cf正如@alexkowalski提到的，​​文件中有一个短参数（-o）的问题不在`main.cf 文件中。

因为 -o 选项可以覆盖基于每个服务master.cf写入的选项，所以参数值是从文件中获取的。main.cfsmtpd_recipient_restrictionsmaster.cf

注意smtpd_recipient_restrictions参数：

smtps     inet  n       -       y       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_reject_unlisted_recipient=no
  -o smtpd_client_restrictions=$mua_client_restrictions
  -o smtpd_helo_restrictions=$mua_helo_restrictions
  -o smtpd_sender_restrictions=$mua_sender_restrictions
  -o smtpd_recipient_restrictions=
  -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
  -o milter_macro_daemon_name=ORIGINATING
------->  -o smtpd_recipient_restrictions=permit_sasl_authenticated, reject

通过注释该行和我不想要的所有其他 -o 行，文件中写入的值main.cf就是采用的值。

答案2

终于，我发现了一个问题！master.cf文件中有一个短参数。

我有：

   -o smtpd_recipient_restrictions=permit_sasl_authenticated, reject

必须是：

   -o smtpd_recipient_restrictions=permit_sasl_authenticated, reject_unauth_destination

需要将参数reject更改为，reject_unauth_destination因为 smtpd 在 sasl 身份验证开始之前拒绝所有传入连接。
