When i finished STMP configrations with correct infomation, and found the function of "Test e-mail recipient" return a error message about "javax.mail.AuthenticationFailedException: 535 authentication failed" and so on.
With the same STMP config,it will work very well at jenkins 1.575.Here is some test results about "Test e-mail recipient" of different jenkins versions:
jenkinss 1.546 Email was successfully sent
jenkinss 1.565 Email was successfully sent
jenkinss 1.575 Email was successfully sent

jenkinss 1.576 Failed to send out e-mail
jenkinss 1.578 Failed to send out e-mail
jenkinss 1.580 Failed to send out e-mail
jenkinss 1.581 Failed to send out e-mail
