If you want to e-mail drawings or whatever attachment that are too large for either you or the recipient here is an alternative to FTP.
Using FileCentral.se (Swedish company but the site is in English) you can send files up to 2 GB for free. I've tried it several times and it worked very well and with great speed.
Another one I've used many times for several years is YouSendIt but it's limited to 100 MB if you want to do it for free.
