You need to create a Postfix instance that holds all mail, and route (transport table entry) mail for this domain to the SMTP port (loopback port) of this new instance. Install the real transport entry in that instance, but HOLD all mail. http://www.postfix.org/MULTI_INSTANCE_README.html http://www.postfix.org/access.5.html http://www.postfix.org/transport.5.html -- Viktor.
