In most of the organizations, they usually have a policy in place for E-mail system to restrict people from sending or receiving mail with very huge attachment.
You can’t use the personal E-mail account to do the task as well because they also have a control for maximum attachment size rule. As far as I know, Gmail can accept up to 20 MB whereas for Yahoo, it can only take up to 10 MB.
In that situation, perhaps you can consider using the online file storage services like Rapidshare, Megaupload to send the mail.
I have tested Rapidshare before using their free service. Even though the upload speed is not fast but at least it serves the purpose. For information, the file kept on their server will be automatically deleted if it has not been accessed for 90 days.
