Use CDex or EAC to convert it to mp3:
www.exactaudiocopy.de www.cdex.n3.net
It'll probably still be too large, e.g. Hotmail has a 1.4 or 2 MB limit (I forget exactly).
Use winrar 3 to further compress it (minimal effect) into a MULTIPART archive.
Then send it in 2 or 3 emails.
Or send it via ICQ or another messenger, etc. pp.
