Run OpenBSD's spamd in greylisting mode.  FTP install should take no
more than 15 minutes, add spamd to /etc/rc.conf.local, reboot and
configure $MTA.  Or just use the OpenBSD box as a bridge/NAT and leave
your current MTA alone.  Adding blacklists to spamd is trivial (just
enable them in the spamd.conf) if you want that later on.
