I disagree; I think there might be.

You're probably going to say 'senders will still try to use pipelining
whether I have it enabled or not.' But I'm going to guess that a
well-behaved sender will pay attention to whether I have it enabled,
while a spammer isn't going to care. So if I have pipelining turned
off, and someone tried to pipeline to me anyway, then I'm justified in
deciding that they're a spammer and I should deal with their message
accordingly -- right?
