Oy! Watch your units!

2Mb != 2MB! (Which is what I think you meant)

I think this one has bene done to death anyway. He's got 400,000 emails
at around 1MB each (For arguments sake. You can scale the numbers easily
for actiual size).

I think the numbers come out to around 200Mbps (That's Mega bits).
Sustained rate

Unless he has some serious bandwidth (We only have around 100Mbps
ourselves and we're a fairly large company :) i.e. at a very well
connected ISP there's no way he's going to get the content out.

What I'm interested in is what the heck is he sending... 1MB per email?
That's a BIG email to be sending out to 400000 people...

Is there any way to reduce the size?
