我被指向了服务 smtp2web前一段时间，但我一直在尝试，但似乎没有用。还有其他人吗？有什么方法可以在 ruby 中实现这一点？
我写了一封电子邮件并将其发送到 lanceJpollard@smtp2web 并立即收到此回复:
Delivery to the following recipient failed permanently:

We recommend contacting the other email provider for further information about the cause of this error.

我知道这有点麻烦，但我一直在开发http://cloudmailin.com做到这一点。它目前处于测试阶段，但目标是始终提供免费版本。
关于http - 有没有SMTP转HTTP的免费服务(Email转POST)？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3553246/
