<pre>static final&nbsp;long MAXUID</pre>
<div class="block">The largest value possible for a UID, a 32-bit unsigned integer.
 This can be used to fetch all new messages by keeping track of the
 last UID that was seen and using:
 <blockquote><pre>

        Folder f = store.getFolder("whatever");
        UIDFolder uf = (UIDFolder)f;
        Message[] newMsgs =
                uf.getMessagesByUID(lastSeenUID + 1, UIDFolder.MAXUID);

 </pre></blockquote></div>
