The list of headers has not changed but the behaviour has. I'm using
Exim 4.86.2 and it doesn't do this. The documented behaviour of the
latest version is that it will sign them if they're absent.
I use a custom pairing of IPv4-only followed by IPv4+IPv6 routers for
all hosts to avoid Google's actively hostile behaviour towards IPv6.
