Are you sure it's duplicated? If it's the same message being routed,
then that should be suppressed. If it's _separately_ sent to a@ and b@
then this can happen, but that's because you then sent two messages.

Or, it could be you're looking with -bt and being thrown by -bt not
quite matching reality. In which case you have my sympathy.

3.11 Duplicate addresses

Once routing is complete, Exim scans the addresses that are assigned to local
and remote transports, and discards any duplicates that it finds. During this
check, local parts are treated as case-sensitive. This happens only when
actually delivering a message; when testing routers with -bt, all the routed
addresses are shown.
