Yes. It it unrelated.

relayhost is the host to which to relay ALL non-local mail. For
incoming mail, you probably only want to pass your own domains to
your internal server (server1). Use transport_maps for that. Consider
the mail loop you get if you have

relayhost =3D server1

on server2, and

relayhost =3D server2

on server1. Using transport_maps to selectively relay mail from server2
to server1 solves this.
