sure. the keyword is "dynamic ip" here.
still, i'm trying to discourage people from doing it, since your machine
might very well be less available than the redundant, diesel-backed big
iron at your isp and eventually cause more bounces.
and if it's not, quietly enjoy your server but don't tell people to do
the same ;), because their admin skills might not be as good as yours,
and a haywire mail server can cause headaches all over the net...
