The answer is not in the RFC. If you used a 1000 messages on the
first MX, you will run into trouble - pronto!!!! It would take forever
sending mail one at at time. Of course, that first MX can expand to
more host/IPs but if its only one or few IPs and there are more MXs,
there are strategies in order to distribute more than one or a few at
a time. Throughput is very important for many.
Well, there is also 'fairness'. While the sender may want to blast their
mailing list at every possible MX and every possible connection on those
MXs for a domain, it's entirely possible the receiver may be more
interested in the sales order that is also trying to come in, rather
than the car rental offers or whatever that are clogging up their servers.
'Throughput' should be for the benefit of the receiver, not the sender.
It's inconsiderate to send using as many threads as possible to a single
receiver.
