If it sends spam from someone other than me, the Received header field makes my /legitimate/ email look more like spam, because both the cat's spam and my legitimate email have the same IP address in the Received header field.

Is that a hobbyist configuration? Is it relevant? It sounds a bit like
a cat and the hat both sharing a NAT. But in a very common high volume
production email scenario used by email service providers, clients and
types of mail are segregated by sending IP address.

Noted that you don't. Just adding my voice: I do want it.
