title: Is it possible to tell Amazon SES to set x-amz-meta header?
body: <p>I configure Amazon SES to store email to <code>S3</code>.
  Also I configure <code>s3fs</code> to mount this mailbox to local filesystem.
  But files are visible with permission <code>0000</code>.</p>
  
  <p>This can be solved by setting <code>x-amz-meta-</code> headers.</p>
  
  <p>Is it possible to write Lamda function which will add this header to new file (email stored at S3)? <a href="https://stackoverflow.com/a/18094544/4632019">like this</a></p>
