Yes, postscreen by design deals only with IP addresses. This is because of the intended use as a lightweight and high speed front-end for postfix. You didn't mention why this client changes IP frequently, or what problem you're trying to solve. You might get better suggestions if you explain the problem you're having in detail. -- Noel Jones
