我们刚刚将客户的网站空间移动到具有弹性IP的亚马逊EC2实例。
我在这里已经非常深入了，因为我对linux操作系统并不太了解
该网站已转移，目前正在我们的测试域http://base5.eu
下工作除了用于发送电子邮件，标准联系表格和申请表格的几种表格外，一切都按预期运作。
php脚本使用sendmail来处理电子邮件的发送。
重要的是要注意，Instance只提供网站，域名的实际邮件帐户都是google邮件帐户。
我们已经设置了指向该域的Google邮件服务器的MX记录。 dns设置为1和1，没有添加PTR记录的选项。
目前正在我们的测试域base5.eu上测试该网站。
似乎发送邮件正在发送邮件，但邮件永远不会被发送。

从环顾四周，我认为它与使用标题的sendmail有关
MAILER-DAEMON@ip-172-31-14-25.eu-west-1.compute.internal
我真的不知道如何解决这个问题，非常感谢任何帮助或建议
