title: webmail is not displaying all To addresses while sending mail
body: <p>I could send mail to multiple ids by using JavaMailAPI.
       Added "To" addresses like ;</p>
  
  <pre><code>message.addRecipients(Message.RecipientType.TO,InternetAddress.parse("srikanth.c@domain.in"));
  message.addRecipients(Message.RecipientType.TO,InternetAddress.parse("risto.j@domain.in"));
  message.addRecipients(Message.RecipientType.TO,InternetAddress.parse("vishnuprasad.v@domain.in"));
  </code></pre>
  
  <p>The mail has been sent to all specified To addresses.
          Outlook and Mozilla Thunderbird are displaying all To addresses. But why webmail is displaying only the last address added, in the above example, webmail is displaying only "vishnuprasad.v@domain.in" in To.</p>
