FIRST, do what mouss suggests and block the spammer through whatever means they are using (broken script, bad settings, etc). Is this a virtual machine? Is this IP(or machine) NAT'd to the main IP? If both questions are yes, then you have a network issue not a Postfix one. NAT routing will change the IP no matter how you setup Postfix. It's how you appear to the outside world, not what you use internally. 'wget http://checkip.dyndns.org' on the "virtual" IP to find out what the world sees you as. In addition, Postfix does not choose interfaces, your network routing table does. If it's not what you want, fix it. (This is beyond the topic of this list.)
