Where can I find mailfromd RPM's for CentOS 6?

I have been trying to locate an RPM for GNU Mailfromd and it's dependencies and have been quite surprised to find it absolutely nowhere on the 'net. Only place I could find any [RPM's were for ALTLinux](http://packages.altlinux.org/en/Sisyphus/srpms/mailfromd/get) . Anyone know where I could find it? I have some advanced filtering needs for postfix and it seems to be the most flexible solution available. I've had a lot of trouble trying to compile the dependencies (also not available it seems) myself (GNU mail-tools, guile, etc). Does GNU have an RPM repository somewhere?
