Marcel:
some possibilities for you:
(1) make your mailserver a gateway for theirs - see the error message
from your log above.
(2) Are you sure their MX record points to their mailserver and not
yours? This message shouldn't even hit your box, if I understand the
setup correctly.
(3) Are you authoritative for their DNS, or are these outside folks
getting different DNS information for domainbla.nl from some other
source?
It's difficult for us to check your DNS information for you, since you
have disguised it...
