Hi I have a server NIS that has a wrong domain name, therefore, everytime that I am receiving an email the user is changed as user@NISDOMAIN despite the fact that my postfix is configured with a mydomain variable. I tried to modify the domain with recipient_canonical_maps or smtp_generic_maps or header_checks without any luck
Someone can help me out, it is not easy to change the NIS since I have some computer that are not easy to access.
