Introduction

SQLWhite is a Postfix policy server written in Perl, based on Lionel Bouton's SQLGrey. SQLWhite serves as an excellent addition to a wide toolset that a Postfix email administator can use to combat spam. It allows the administrator to create policy which allows or denies incoming email by source address, destination address, and MTA IP address/domainname. SQLWhite also has support for wildcarding, which makes policy description very easy. Furthermore, SQLWhite's policy can be defined by the Xerxes E-Mail Administrator through a web browser.
