亚马逊SES连接通过SMTP超时

郭凯
2023-03-14

我试图通过AWS SES发送一封带有SMTP的电子邮件，我正在使用这个org。springframework。邮政javamail。JavaMailSender。发送spring boot starter mail（spring boot 2）项目的方法，我收到了这个错误堆栈：

这个错误表明由于连接失败而无法执行，这一点非常明显，但是，当我从爱尔兰运行这段代码时（SES服务上的同一个区域正在运行，并且配置相同），它可以工作。

现在，我的问题是：

是否可以从该服务不可用的区域运行AWS SES？是否可以将endpoint设置为可用区域？（忽略延迟和其他相关信息）。这个错误是关于另一个我没有看到的东西的意思吗？

谢谢

我的五分钱。检查亚马逊服务器url（即email smtp.us-east-2.amazonaws.com）是否在末尾没有空格：“email-smtp.us-east-2.amazonaws.com”。

似乎在巴西，发送SMTP端口25通常被阻止以防止垃圾邮件。您可能需要在不受此禁令影响的服务器上设置此选项。要么通过巴西的托管中心，要么通过邻国的某个地方。
