Droid message emails with .wav files attached

[RustyCP]

I just bot a Motorola Droid RAZR cell phone that I use to receive Emails with attached .wav message files from my MagicJack IP phone service. Apparently the Poweramp app is the only one that works on Droid phones to play .wav files! Anyway, how do I get the Droid's Email function to play the attached .wav file automatically, instead of my having to laboriously save the file to a folder, exit the Email function, go into the apps folder, launch Poweramp, and then play it there??? Thanks!
