Question

尝试使用以下代码发送电子邮件时：

Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("noreply@${appId}.appspotmail.com", "Some Name"));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(emailAddress, name));
msg.setSubject("Subject");
msg.setContent(email.toString(), "text/html");

Transport.send(msg);

我收到以下错误：

com.example.web.EmailController newsletterSend: Email not sent to
"real mail here".
javax.mail.SendFailedException: MailService IO failed

任何想法为什么？更令人担忧的是，这也消耗了我的配额。

您应该发布您的代码。我正在工作

public static String SendMail(String htmlText,String email,String sub)
{       
    String SMTP_AUTH_USER ="xxxxxxxxxxx@gmail.com";     
    Properties props = new Properties(); 
    Session session = Session.getDefaultInstance(props, null);   
    try 
    { 
        Message msg = new MimeMessage(session);            
        msg.setFrom(new InternetAddress(SMTP_AUTH_USER, "RQT")); 
        msg.addRecipient(Message.RecipientType.TO,new InternetAddress(email)); 
        msg.setSubject(sub);            
        msg.setContent(htmlText, "text/html");
        Transport.send(msg); 
        return "";              
    } 
    catch (Exception e) 
    {
        return e.getMessage();
    }


}

根本原因是电子邮件地址包含在"中，例如"user@example.com"。我有reported the problem，希望下次我们会收到更好的错误消息。
