Perhaps the manual isn't clear. That option might better have been
called relay_match_host_or_sender_address. It means that *either* the
host is acceptable, *or* the sending address (envelope from) is
acceptable. (The default state uses AND rather than OR.) The list of
sending addresses that are acceptable is specified in
sender_address_relay. If it is empty, all sender addresses are
acceptable. That is why setting
sender_host_reject_relay = *
relay_match_host_or_sender = true
lets everything in. In fact, setting relay_match_host_or_sender without
setting anything in sender_address_relay is a nonsense. I will lock out
that combination in the next release, I think.

I hope I've shed some light. I already had a note to add more
explanation about sender_address_relay, so you are not the first to have
problems. Maybe I should try to draw a flowchart-like diagram of the
checks that Exim applies.
