See the resulting master.cf below.

I also thought I should explain my setup a little. What I want to achieve is the
ability to filter some domains while leaving out others because some customers
may prefer their mail filtered while others may not. I want to achieve this on
one machine. I don't want to setup two separate boxes nor two instances of
postfix. I read that all I need is to use the /etc/postfix/access file with
entries like these:

  domains1.tld FILTER smtp-amavis:[127.0.0.1]:10024
  domain2.tld OK
  domain3.tld FILTER smtp-amavis-mailzu:[127.0.0.1]:10026
  e.t.c.

Is it possible to achieve this without setting the "-o
receive_override_options=no_address_mappings" in the smtp section of the
master.cf?
