title: How to retrieve the contact list of an email mailbox?
body: <p>I'm working on 'Reputation Management in Email Systems' as my MSc research project.
  The objective is to evaluate the reputation score of each contact/email address (in the contact list) of an email user and share the reputation information with other email users. 
  I'm using Apache James for the implementation of the reputation server. </p>
  
  <p>The problem I'm facing is <b>how to retrieve the contact list/email addresses pertaining to a particular email user/mailbox.</b> </p>
  
  <p>In SMTP, IMAP email server architecture, is there a common way to retrieve a contact list? Or is the contact list maintained purely at the email client side?</p>
  
  <p>Thanks,<br>
