代码如下：我在发送email 的时候加入了多线程。可能是500封，也可能是1000封。或2000 - 4000.

transport = session.getTransport("smtp");

transport.connect("email-smtp.us-east-1.amazonaws.com", UserInformation.emailUser, UserInformation.emailPassword);

for (SObject contact : result.getContacts()) {

if (contact.getField("Email") != null) {

if (!transport.isConnected()) {

transport.connect("email-smtp.us-east-1.amazonaws.com", UserInformation.emailUser, UserInformation.emailPassword);

}

Thread thread = new Thread(new SendMessageRunnable(tasks,

transport, sender, emailTemplate,

contact, attachments, documents));

flag = true;

thread.start();

listThread.add(thread);

}

}

大家帮忙看下。

Answer 1

如果我在下一个线程启动之前 sleep(1000); 这样这个问题能解决吗？

Answer 2

服务器限制了你的发送频率，发太狠了
