If 62.x.x.x is on your network and you definitely want to
allow relaying from it, add 62.x.x.x to host_accept_relay.
If it's not on your network then it's good not to allow this
kind of relaying.
Be aware that exim tries host_accept_relay entries in order
so it rejects messages if you have a *.domain entry before
the ip network/mask type entries and the host doesn't have a
working reverse DNS entry. So I would set host_accept_relay
up like this:
