If you're doing the DKIM signing with amavis, here's a possible fix (taken from https://git.dotlan.net/dhoffend/ansible-role-kolab/blob/master/templates/amavis/65-dkim.j2#L17):
$signed_header_fields{'received'} = 0;

The issue is probably caused by Postfix being configured to remove the Received: field for outgoing emails.
