使用外部 smtp 服务器发送电子邮件时达到 Amazon EC2 邮件限制 [英] Amazon EC2 mail limit reached while using external smtp server to send emails

问题描述

嗨
我正在使用 grails MailSender 服务(在下面使用 Java Mail API)从 Amazon EC2 linux 实例发送大量电子邮件.我已经将邮件 API 配置为使用端口 25 上的外部 smtp 服务器来发送电子邮件，并且我可以从外部电子邮件服务器日志中验证电子邮件确实是由他们发送的.

Hi
I am sending lots of emails from and Amazon EC2 linux instance using grails MailSender Service(Uses Java Mail API underneath). I have configured the Mail API to use an external smtp server on port 25 to send the emails and I could verify from the external email server logs that emails are indeed sent by them.

但是亚马逊 AWS 给我发了一封电子邮件，说我达到了他们的电子邮件发送限制，无法从 SMTP 端口 25 发送.

But Amazon AWS has sent me an email saying that I reached their email sending limit to send out of SMTP port 25 .

当我一直使用外部 smtp 服务器发送电子邮件时，我无法理解我是如何达到限制的.此外，我确实在从 Java Mail API 连接到外部 smtp 服务器时遇到间歇性连接超时错误.

I am not able to understand how did I reach the limit when I have always used external smtp server to send emails. Additionally, I do get intermittent connection timeout errors for connecting to the external smtp server from the Java Mail API.

非常感谢任何帮助.

谢谢

推荐答案

出站电子邮件有一个限制以阻止垃圾邮件(我认为).您可以请求覆盖此:https://aws-portal.amazon.com/gp/aws/html-forms-controller/contactus/ec2-email-limit-rdns-request

There's a limit on outbound emails to stop spamming (I presume). You can request to override this: https://aws-portal.amazon.com/gp/aws/html-forms-controller/contactus/ec2-email-limit-rdns-request
