Please review the Postfix 2.6 RELEASE_NOTES file, in particular the section titled "Major changes - milter support". I suggest that you also review the RELEASE_NOTES files for all the Postfix releases since Postfix 2.3.3. I have included these files with Postfix, and I hope that some helpful distro maintainer has not removed them. Wietse
