Use of a chess engine in online games

Im playing an opponent for the second time. He is obviously using
some sort of chess engine or electronic chess board to aid him in the
game.
What action can I take to ensure the game is not ended with my
rating being effected?
You can email me back at therin@holly.colostate.edu for fast response.

Thanks

How are you so sure? Tell everyone the IDs of the games, and someone who knows more about
chess than me might be able to tell if you are right.

As for the rating, you can always play against me to recover the lost points...

or against me, and you'll be guaranteed a good game - may not be as good as an engine.....
