The relocated_maps response is reported while rejecting a non-existent
recipient. In fact, the relocated_maps result has precedence over
relay_recipient_maps:

The logic is (file smtpd_check.c, function check_rcpt_maps):

1) search the recipient canonical maps
2) search the global canonical maps
3) search the virtual alias maps
4) report "user has moved" from relocated_maps, "user unknown
in virtual alias table" and other things that resolve to
the error: delivery agent
5) search local_recipient_maps, virtual_mailbox_maps or
relay_recipent_maps depending on the recipient domain.

So the only explanation I can come up with is that you are
using tables in multiple and/or otherwise unexpected places.
