If you review the very, very, lengthy discussions on this topic, you will find that we all agree that the vast majority of SMTP deliveries are to a single recipient, on the order of 99%. Even though it is *possible* to do multiple deliveries, it is uncommon. Hence believe that if we required single deliveries, the amount of extra traffic would be very small. This is not a new argument. My mail system uses qmail which has been doing single deliveries since 1998 and it has always worked well.
