Can't send large e-mail attachment

From Wiki-FL

FirstLink e-mail servers allow attachments up to 45Mb. However, the ISP of the person you are sending to may not allow the size you are trying to send. If the e-mail times out while trying to send, raise the timeout setting in your e-mail client. Depending on your internet connection, the attachment may not be able to be compiled in the time frame your e-mail client gives. One option is to zip, rar or tar the attachment to decrease its size.
