Have a look at Mimedefang http://www.mimedefang.org This is what I use & install for organisation wide spam & virus filtering. Another one I have come across is http://www.sng.ecs.soton.ac.uk/mailscanner/ but I have never used it. And yes use the Milter API this is what its designed for. > 1) is sendmail with FC1.0 compiled with the Milter API enabled ? > I'm not sure but I expect that it is. > 2) if not, is there anything I need to consider in downloading the source > and installing from > that - other than following the normal instructions ? If you mean the Sendmail source I wouldn't. I'd download the fedora sendmail src rpm and rebuild it with what ever extra options you require. http://distro.ibiblio.org/pub/linux/distributions/fedora/linux/core/1/SRPMS/ sendmail-8.12.10-1.1.1.src.rpm Regards John
