Ok. It's some smarthost router, isn't it?
You should avoid using this router for address verification as it will
always succeed.
verify = no
as option for your smarthost router should do the trick. But
additionally you'll need to install some router which is able to verify
the addresses. Probably it will be a dnslookup router, and, as order
matters, it has to be *after* the smarthost router.
