Question

我在AWS Elastic Beanstalk上运行Wordpress 4.2。我正在使用一个使用WP电子邮件API发送电子邮件的插件，该电子邮件API使用服务器（即Elastic Beanstalk）的内部邮件系统。

问题：应用尝试发送到我的大学电子邮件（我们称之为.uni.edu）的电子邮件失败，并且在发送到我的标准Gmail时它们确实有效。

有趣的是，我在本地运行相同的应用程序没有问题。与应用程序关联的电子邮件发送正常 - 显然，Elastic Beanstalk特别试图将消息中继到.uni.edu服务器的方式存在一些问题。也许.uni.edu服务器将其作为垃圾邮件发送（当从Elastic Beanstalk发送时，而不是通过我的本地系统发送时）并将其弹回，但我没有足够的经验来诊断它。

是否有人建议直接对此问题应用某种修复方法，或者创建某种解决方案的设置（例如，在Elastic Beanstalk上设置一些内容以非默认方式发送电子邮件的可能性较小有问题与大学电子邮件服务器一起工作）？

Answer 1

这听起来与另一个关于电子邮件的近期问题非常相似：

http://stackoverflow.com/questions/29808262/unable-to-send-emails-from-linux/29810884#29810884

您的ec2实例是否有关联的外部DNS？是否有与之相关的公共IP。您需要应用某种类型的修复，以便您的外发电子邮件的域名不是webapp@ip-172-31-41-109.ec2.internal
