最近一直在使用郵件發送功能，老是遇到問題，後面才找到，原來並不是程序問題引起的，我吧問題整出來，
javax.mail.SendFailedException: Sending failed; nested exception is: class javax.mail.MessagingException: 554 MI:STC 0,smtp10,DsCowLC7LwPACzRN7qcQAA--.2883S2 1295256512 at javax.mail.Transport.send0(Transport.java:218) at javax.mail.Transport.send(Transport.java:80) at mbspublic.mail.sendmail.sendmsg_mediaset(sendmail.java:1302) at mbspublic.mail.sendmail.main(sendmail.java:1962)
其實這個問題是163服務器問題，你的郵箱發件平率過高，被暫時限制掉了
