It depends on what Sendmail passes to mlfi_connect(ctx, hostname, addr)
as hostname. If it's the same like Postfix -- [some.ip.addr.ess] -- then
enabling it for both MTAs would make no difference IMHO.

I don't have Sendmail so I can't check this, but basically one just has
to dig through the logs and find a Sendmail session with a no-rdns
client. The interesting part are the milter-greylist lines then:
