【问题描述】：
我在我的 Google Compute Engine 实例上安装了Postfix 邮件服务器，并使用Google Apps SMTP relay service 对其进行了配置。这很好用，我可以从我的服务器发送电子邮件。
问题
当我向与用于配置 Google Apps SMTP 中继服务的电子邮件地址相同的电子邮件地址发送电子邮件时，它无法接收。
我已经通过以下方式对此进行了测试：
echo "Test email description" | mail -s "Test mail" -a "From: info@mydomain.com" info@mydomain.com
当我跟踪/var/log/mail.log 文件时，您可以看到邮件已发送，但当我查看收件箱时，没有收到任何电子邮件。
