Do you believe e-mail traffic to be of sufficient quantity to be even
noticeable at a high-traffic interchange point like MAE-East under high
load conditions?

This strikes me as micro-optimization.  Next to web and news, let alone
something like streaming audio or video, e-mail is barely a blip until you
get down to the individual network level, at which point I agree that
qmail may not be the best choice for all circumstances.
