我正在尝试在groovy脚本中使用javamail通过gmail发送电子邮件.我在网上看了很多地方,到目前为止还没能让它运转起来.我在运行脚本时遇到的错误是:

DEBUG SMTP: useEhlo true, useAuth false
DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 25, isSSL false
Caught: javax.mail.SendFailedException: Send failure (javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25 (javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?))

它似乎尝试使用端口25,即使我已经指定它应该使用端口587.有谁知道可能导致此问题的原因,我已经使用telnet连接到端口587上的smtp服务器,并且thunderbird使用端口587具有STARTTLS安全性,并且能够使用smtp服务器成功发送邮件.这告诉我它不是阻塞端口或连接问题.这是我用来尝试发送电子邮件的代码:

import javax.mail.*
import javax.mail.internet.*

private class SMTPAuthenticator extends Authenticator
{
    public PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication('email@gmail.com', 'password');
    }
}

def  d_email = "email@gmail.com",
        d_password = "password",
        d_host = "smtp.gmail.com",
        d_port  = "587", //465,587
        m_to = "email@gmail.com",
        m_subject = "Testing", …

任何人都可以帮我使用代理使用JavaMail API发送邮件吗？

我用的代码用来发送简单的邮件

import javax.mail.*;

  public static void main(String args[]) throws Exception
  {

  }

  public void postMail( String recipients[ ], String subject,String message , String from) throws MessagingException

        Properties props = new Properties();
