The problem i have with the smtp_generic_maps is that when I put
in the map it works, but it also changes the RCPT TO addresses.
So if I send from esimard@... to wietse@... it will
now try to send emails to wietse@... which does not exist.
Is there a way around that?

Use smtp_generic_maps on the network boundary, to transform addresses
that are valid only inside the network, into addresses that are
valid outside the network, without exceptions.
Use aliases on the network boundary MTA, to route mail that enters
the network from outside, to whatever addresses you use internally.
