我在 AMI Linux 上运行 Postfix 2.6.6。此 Postfix 服务器的用途是：
1) 为网络上的客户端计算机发送邮件。
2）接收来自不同用户名和域名的电子邮件地址的外部电子邮件，并将这些电子邮件转发到另一个外部电子邮件地址。例如，未知用户向[电子邮件保护]然后 Postfix 将其转发到[电子邮件保护]。
#1 工作正常。但是，每当任何外部用户发送电子邮件到[电子邮件保护]，Postfix 给出“中继访问被拒绝”消息。
以下是日志：

我花了很多时间排除故障并寻找答案，但似乎我能找到的所有以前的帖子都与我的情况略有不同。现在我不知所措。
答案1
您的 postfix 无法识别它应该接受发往 example.com 的电子邮件进行传送，它认为 gmail 正尝试使用您的电子邮件服务器作为中继。
看一下http://www.postfix.org/postconf.5.html#mydestination并添加域名example.com。
