Mail.app Play audio on receive

[Powermaster]

Hello all.

I have Vonage and part of the cool things about it is the voice-mail. The Voice-mail will automatically e-mail me a copy of the audio. I would like to have the audio file play automatically as soon as it is received. I am currently running mail.app on Mac os 10.3.9 I know its getting dated but, it's all I can get. :-)

Please let me know if you know of a way to do this. I imagine there is a way using apple script and a mail rule but, I am just not that great with apple script. The audio file is just a simple .wav file.

Thanks for you help!
