I don't agree with Greylisting either for all the reasons cited - however 
- whilst we are used to the fact that email works quickly, we at the same 
time shouldnt be building the expectation that it is 'guarunteed' quick.

Sure, it'll be quick a vast proportion of the time - but we should expect 
delays on occaision. And make sure people know this.

People relying on email for mission-critical time-sensitive delivery of 
information should always have a plan B. (its called, often, _picking up 
the phone_).
