Ruby on rails Rails不在AWS上发送电子邮件

我正在尝试从我的Rails应用程序发送确认电子邮件。在我的开发环境中，它可以完美地工作（在ubuntu中）。但是，当我尝试在我的AmazonAWSEC2实例中发送电子邮件时，它不起作用。我得到下一个错误日志：

我看到一条连接被拒绝的消息，我想我应该配置一些安全凭据或打开一些端口。。。但我不知道

提供更多细节。我的电子邮件服务是由Zoho提供的，我配置了一些帐户。我用Route 53在AWS中配置了两个MX记录集。邮件正在工作，我的意思是，我可以发送和接收来自其他帐户（如gmail或hotmail）的电子邮件到我的zoho帐户。正如我所说，电子邮件服务正在开发中使用这些帐户（这是另一个ubuntu）。

您是否在专有网络中运行此应用程序？如果是，请验证NAT实例的安全组是否允许SMTP入站/出站通信。如果它是一个经典的EC2实例，请在实例的SG中执行相同的操作。

您是如何尝试发送电子邮件的？我不知道您的确切意思，我使用的是一个EmailService类，它在Rails中扩展了ActionMailer。我不知道它在幕后是如何运作的。我只知道它在我的开发环境中工作得很好。我可以发布一些代码，但我认为它与代码无关。我假设您不在ec2上的登台环境中？您是否为非登台环境配置了邮件设置？尽管我们正在测试，但它将是生产环境。我还没有配置任何与电子邮件相关的内容。我应该配置什么？好的，我想我必须阅读SES，对吗？可能是重复的
