ber, i use a service at dyndns.com that does what you want for not a whole lot of cash, about 40 dollars a year.
we are in a louisiana, a hurricane prone area.
i purchased the service when our internet provider, AT&T, would not stay working. i left them for a cable internet company.
it use to be called "mailhop" but now i see it is called "sendlabs mx backup"
i do not need toliet paper either but it is good have and use.
