Send file by email directly from my website

Hello, sorry for my english.
is there any plugin for wordpress or form where people can enter on my site and
send the specific “content” of a post to email it?
My site offers some audio files in mp3 for download.Gostaria that the person had the option, instead of downloading this file pro audio pc her, she could send it straight to your email, as an attachment to low it later, where she wanted.
Is there any way (whether in form or plugin) that I can make this option available on my website?
