If the ISP of the person you wanr to send the music to has a small limit you can use a file splitter to split the file into 2 or more segments and then send each part as an attachment, waiting until you get confirmation from the receiver that they have cleared their mail off the server. There are several splitters (freeware and paid) available, I use Dariolius from
http://www.kanastacorp.com,
its free ware. You just split the file however you like, fixed number of segments, or segments of a particular size, etc and it will split the file and produce a small program to put the file back together at the other end. You just send the parts and the program as attachments, the person at the other end just puts all the parts and program in a folder and then just double clicks the program icon, they don't have to have dariolius installed. Then they can do what they like with the file.
