You should use morercpthosts, because Dan knows what he's doing.

I can't answer that; this is a case of 'profile, don't speculate.' If you're
using just rcpthosts, and your performance is acceptable, then obviously you
_can_ just keep doing what you're doing.

Could be (see above). However, total throughput isn't the only test of
load. You should install qmailanalog, if you haven't already. Look at
your average concurrency. If it is high, then you should _definitely_
use morercpthosts--and also use concurrencyremote to allow more
concurrent deliveries.
If your concurrency is very low, you probably don't have to change
anything.
