500mb by email!!!!!! no no no no no no no!!
to the site
you will find that most email service providers give people inboxes of no bigger than about 10mb. I know there are some that give large amounts, but this is not common.
Also if you are only on 150k with the upload speed it would take hours to send a file that size. My best advise is to put the file you are trying to send on cd and post it!
