That depends on how they are sending it, of course.  Webmail usually just
has the IP of the host, and I imagine quite a few others around here have
their own personal servers that could also be used for this, one way or
another.

Then of course there are things like Blackberries and iPhones that can
send email themselves, and are likely to have IP addresses that are linked
to something besides their current location.
