Assume that the majority of the outgoing mail volume from a list
server depends on incoming mail to this list server.

If you reduce the incoming volume to this list server, there should
also be less outgoing volume.

One can also assume that delivering spam[0] to a will be more expensive
than delivering non-spam, since some servers use delaying tactics when
they receive the former.

[0] - As decided by the receiving server.
