At home, I do that on the sending side, and it's independant from the IP
address. The receiving side has a static address and accepts anything to
mydomain.dom and *.mydomain.dom, from where I get the mail with
fetchmail. Having to use fetchmail and the misconfigured systems that
deny mail from dynamic addresses are the disadvantages. Otherwise, it
works perfectly well since years now.
