app里使用163郵箱發送郵件，被163認為是垃圾郵件的坑爹經歷！_ ！

最近有個項目，要發郵件給用戶設定的郵箱報警，然后就用了163郵箱，代碼是網上借來的^^，如下：

            }
            return sendStatus;
        }
    }
}

然后，隨便輸入了個標題和內容測試，沒有問題。於是，把報警信息整理好，寫入標題和內容，杯具的事情發生了，一直無法發送成功，返回錯誤信息如下：

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這個網址一看，是被作為垃圾郵件了！@ ！

開始了換主題、換內容，換了N次后，才終於不被認為是垃圾郵件了，坑爹的，最啃爹的是，換了N都詞語后都不行后，把“：”（漢語輸入法）換成“:”（英文輸入法），好了，這是什么規則？！！！

 

ps：上面的代碼需要添加activation.jar、additionnal.jar、mail.jar，可以自行百度下載。
