A system should filter unwanted events as early in the pipeline as it 
can.

That is more efficient.

I don't want my mail server receiving and delivering stuff that is going
to be certainly deleted later; it wastes bandwidth and cycles.

It's also very simple to implement "drop connections from this
mail host" not to mention simpler to convince yourself that the rule
is correct.

Plus: what if I don't want to get *anything* from that server, list or 
not?
