Hi there, I'm hoping someone can help, I am a Graphic designer and the majority of the .MP4 files (Audio and visual) I download and use are well about 250mb.. I need to send them back and forth through mail often but it wont allow me and I've had to come up with awkward round-abouts as I cannot figure out the problem. However, it's not very professional towards clients. Is there anyway i can change the Mail File Attatchment  size to unlimited..? Thanks In Advance!
