need to create multiple email addresses

Hi, I haved recently set up a wesite for school which will allow me up to 500 emails however my host does not provide a script within the cpanel to create multiple e-mail addresses at once. I therfore have to use the cpanel to create them one at a time. I have all the information in a csv file. Can anyone suggest where I may find a script that will let me use a csv file or rtf file to cretae multiple email addressea at once, otherwise it will take me hours to create the addresses for the entire school.

Cheers in advance

Wheelie.
