Indy 10 - 从GMail帐户发送邮件时，IdSMTP.Send（）挂起 [英] Indy 10 - IdSMTP.Send() hangs when sending messages from GMail account

问题描述

我正在尝试使用gmail帐户（Delphi 7，Indy 10）发送一封电子邮件，其中包含以下设置：

TIdSmtp：

  Port = 587; 
 UseTLS：= utUseExplicitTLS; 
  

TIdSSLIOHandlerSocketOpenSSL：

 code> SSLOptions.Method：= sslvTLSv1; 
  

一切似乎都设置好了。我得到这个回应：

连接到74.125.77.109。 
 SSL状态：之前/连接初始化

 SSL状态：SSLv3写客户端hello A

;位= 128; version = TLSv1 / SSLv3; 
  

然后它挂起并没有完成。电子邮件不发送。可能是什么问题？

解决方案

问题很简单。我没有足够的耐心，应用程序没有挂起，有很长的超时时间。超时是设置错误的结果。

I am trying to send an e-mail using gmail account (Delphi 7, Indy 10) with these settings:

TIdSmtp:

Port = 587;
UseTLS := utUseExplicitTLS;

TIdSSLIOHandlerSocketOpenSSL:

SSLOptions.Method := sslvTLSv1;

Everything seems to be set ok. I get this response:

Resolving hostname smtp.gmail.com.

; bits = 128; version = TLSv1/SSLv3;

And then it hangs and doesn't finish. E-mail is not sent. What can be the problem?

解决方案

The problem was simple. I was not patient enough and application didn't hang, there was long timeout. The timeout was result of wrong settings.
