title: Is there a google api to verify if a gmail is valid from java?
body: <p>I have to debug a google contact management app and the problem is sometimes there is some synchronization problem because some mail are deleted on google servers but they appear active in application.</p>
  
  <p>Is there a google api to check if a mail is still active ?
  If not, what do you think would be the best way to  validate a gmail from a java application ?</p>
  
  <p>Thanks.</p>
