Complain to your ISP to fix his DNS.
$ host 126.96.36.199
$ host wireless-067-118.tele2.co.uk
wireless-067-118.tele2.co.uk does not exist (Authoritative answer)
Relaying only defines the hosts who can use your box as a mail HUP
(aka smarthost or relay). So it accepts any mail from them and sends
it to the destination.
If there is no relay control, it is a open relay, which will put you
on a black list sooner than you think, as a open relay can be used by
spammers to get their stuff distributed.
