Amazon Web Services SES smtp超时

Question

我使用AWS SES在我的Rails 4 Web应用程序中向客户发送通知电子邮件。 发送电子邮件时，我发现很多时候由于SES中的SMTP超时错误导致电子邮件发送失败。 最后，经过一些重试，电子邮件被发送，但我不想要这些重试。

我不必在我的应用程序中更改任何内容，以便可以发送电子邮件，它可以在重试后运行。

我附上错误日志：

Answer 1

看起来它只是通过更改我的Rails应用程序中的SMTP端口配置来工作。 我将端口更改为587。

Answer 2

解决方法是设置rails应用程序用作smtp服务器的本地smtp服务器。 本地smtp服务器将中继到SES。 如果通过ses中继失败，像postfix这样的本地smtp服务器将自动重试，因此你的rails代码只需要将邮件排队一次。
