title: Cannot send message to certain channel using discord.py
body: <p>I am currently working on a discord bot, and I happened to run into this issue. I am relatively new to <code>discord.py</code>, and this is probably a newbie issue, but I would appreciate the help anyway :)</p>
  
  <p>My current code: </p>
  
  <pre><code>@bot.listen()
  async def on_message(message):
          messagecontent = message.content
          chan = message.channel
          if messagecontent.startswith("--"):
                  pass
          else:
                  embed=discord.Embed(title="Gathering Response...", color=0x00ffff)
                  msg = bot.send_message(destination=chan,embed=embed)
  </code></pre>
  
  <p>When I run this and send a message, I receive no error message, or any feedback at all. It just does nothing. I would appreciate any help on this issue.</p>
