最近一直在使用邮件发送功能，老是遇到问题，后面才找到，原来并不是程序问题引起的，我吧问题整出来，
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)
其实这个问题是163服务器问题，你的邮箱发件平率过高，被暂时限制掉了
