【问题描述】：
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 API 使用服务器的（即 Elastic Beanstalk 的）内部邮件系统。
问题：应用程序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，但它们在发送到我的标准 gmail 时确实有效。
有趣的是，我在本地运行相同的应用程序没有任何问题。与该应用程序关联的电子邮件发送良好 - 因此显然 Elastic Beanstalk 尝试将消息中继到 .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（从 Elastic Beanstalk 发送时，而不是通过我的本地系统发送时）接收并将其退回，但我没有足够的经验来诊断这一点。
有没有人建议直接对这个问题应用某种修复，或者创建某种作为解决方法的设置（例如，在 Elastic Beanstalk 上设置一些东西，以不太可能的非默认方式发送电子邮件使用大学电子邮件服务器时遇到问题）？
这是来自 /var/mail 的日志：
