The secret is a line similiar to:

  virtual_maps = hash:/etc/postfix/virtual

in the '/etc/postfix/main.cf' configuration.  The '/etc/postfix/virtual'
file contains lines like:

  domain1.com           domain1.com
  emaila at domain1.com    foo at this.machine.com
  emailb at domain1.com    bar at this.machine.com
  emailc at domain1.com    fred at flintstones.org

  domain2.net           domain2.net
  emaila at domain2.net    moo at this.machine.com
  @domain2.net          spam at somewhere.else.com

after being changed, the 'hash' version (binary representation) must be
updated by running:

  sudo postmap /etc/postfix/virtual

Hope that helps,
