如何在单个 IdSMTP 连接中发送多封电子邮件? [英] How to send several emails in a single connection of IdSMTP?

问题描述

我在 C++Builder 6.0 专业版上使用 Indy 10.

I am using Indy 10 on C++Builder 6.0 Professional Edition.

我的 SMTP 服务器对特定时间间隔内的连接数施加了限制，因此我需要使用同一连接发送多封电子邮件.是否可以?我该怎么做?

My SMTP server imposes a limit on the number of connections in a certain time interval, so I need to send more than one email using the same connection. Is it possible? How can I do that ?

我已经能够连接并在每次连接时发送一封电子邮件.

I am already able to connect and send one email on each connection.

非常感谢您的帮助.

推荐答案

可以在一对Connect()之间多次调用TIdSMTP.Send()/Disconnect() 调用，根据需要为每个 Send() 调用调整 TIdMessage.

You can call TIdSMTP.Send() multiple times between a single pair of Connect()/Disconnect() calls, adjusting the TIdMessage as needed for each Send() call.

IdSMTP1.Connect;
try
  // prepare TIdMessage as needed...
  IdSMTP1.Send(IdMessage1);

  // prepare TIdMessage as needed...
  IdSMTP1.Send(IdMessage1);

  // prepare TIdMessage as needed...
  IdSMTP1.Send(IdMessage1);
finally
  IdSMTP1.Disconnect;
end;
