No. Use a mail reader that distinguishes quoted text properly. Less cheekily, I think an important part of interleave quoting is editing the original email. I think it's poor form to quote an entire 4 paragraph email and put your 1 line answer at the bottom. The better way is to trim it down as much as possible without completely losing the original meaning and then reply. Quite often this you can trim back to a single sentence which is a direct questions. And any sort of background introductory paragraphs can be snipped away completely.
