title: Forwarding a huge amount of messages using telethon
body: <p>For some reason I need to forward near 30 000 messages from one chat to itself. I wrote something like that:</p>
  
  <pre><code>messages = client.get_messages(chat, None)
  for i in range(0, 30000, 100):
      client.forward_messages(chat, messages[i: i + 99])
  </code></pre>
  
  <p>But I exceed flood rate</p>
  
  <pre><code>telethon.errors.rpcerrorlist.FloodWaitError: A wait of 441 seconds is required
  </code></pre>
  
  <p>Can I somehow get around it?</p>
  
  <p>By the way, if it possible to get messages from before particular date I also will be appreciated. </p>
