My experience with a HP at Curtin Uni shows that generally mail delivery 
is instantenous except when the main gateway is saturated. But never more 
than 6 hours delay (this is for the 1200 to 2200 hours period of maximum 
net usage).

MS-Mail (and Exchange) are designed around a "dial-out" service and not a 
direct connect network. Sendmail has options for a dial-out setup (only 
dial when there is either n messages in the queue or x hours have passed).
This is an area not many people look at, there are just too many options!!
