      Hi,

      I would use transport maps. Just look at the /etc/postfix/transport file, there are instructions about how to config it. You may also need to change /etc/postfix/main.cf to activate the transport map. Try using these lines at the end of transport.

      example.com       smtp:bar.example:25
      .example.com      smtp:bar.example:25

      You should change parameters above to your situation. Those lines will send every email coming to example.com to the server bar.example, using smtp and port 25. 

      Read carefully transport file infile instructions. At the end, there is a section "CONFIGURATION PARAMETERS", that applies to main.cf and is very important.

      Cheers,

      Handle null clients that punt all mail to a relay by not including
      $myorigin (or anything else for that matter) in $mydestination and
      by setting a relayhost to point to the mailhub.  Plus some reasonable
      handling of root, ...
