.+@.+ Should do the trick

  I considered that one, but I'm sure there's some system out there which doesn't require an account name ahead of the "@" symbol. We're shooting for 100% accuracy, after all. ;)

    In that case, let me improve it further :-) /@./ Though I'm not really sure there could be an email without username part.
