For dynamic IPs, like those assigned by home ISPs is not useful (besides stupid) adding the ISP's range (since the spammers will probably be windows machines using an IP from the same IP range than yours). What I did was implementing SMTP authentication, and then I can send e-amil from my e-mail client at home without my server being an open relay and without allowing the full ISP IP range to send mail through my mail server.
