最近有个项目，要发邮件给用户设定的邮箱报警，然后就用了163邮箱，代码是网上借来的^^，如下：
package com.smartdoorbell.util;
import android.os.AsyncTask;
import java.util.Date;
import java.util.List;
import java.util.Properties;
import javax.activation.CommandMap;
import javax.activation.MailcapCommandMap;

import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

JieAuthenticator jieAuth = new JieAuthenticator(user, password);
Session session = Session.getInstance(properties, jieAuth);
// 创建一个消息
MimeMessage msg = new MimeMessage(session);
// 设置发送人
msg.setFrom(new InternetAddress(user));
// 设置主要接收人
if (emailTos != null && !emailTos.isEmpty()) {
int size = emailTos.size();
InternetAddress[] addresses = new InternetAddress[size];
for (int i = 0; i < size; i++) {

}
@Override

sendEmailBg();
sendStatus = SendStatus.SENDOK;
} catch (Exception e) {
e.printStackTrace();
sendStatus = SendStatus.SENDFAIL;
}
return sendStatus;
}
}
}
然后，随便输入了个标题和内容测试，没有问题。于是，把报警信息整理好，写入标题和内容，杯具的事情发生了，一直无法发送成功，返回错误信息如下：
com.sun.mail.smtp.SMTPSendFailedException: 554 DT:SPM 163 smtp11,D8CowACnIsnYuENXzwhNBw--.59036S2 1464056024,please see http://mail.163.com/help/help_spam_16.htm?ip=121.34.169.53&hostid=smtp11&time=1464056024
去http://mail.163.com/help/help_spam_16.htm?ip=121.34.169.53&hostid=smtp11&time=1464056024这个网址一看，是被作为垃圾邮件了！@ ！
开始了换主题、换内容，换了N次后，才终于不被认为是垃圾邮件了，坑爹的，最啃爹的是，换了N都词语后都不行后，把“：”（汉语输入法）换成“:”（英文输入法），好了，这是什么规则？！！！
ps：上面的代码需要添加activation.jar、additionnal.jar、mail.jar，可以自行百度下载。
