There are clients for a number of operating systems,
http://www.dyndns.org has a list and also does the
kind of service you are looking for. Alternatively,
smoothwall has a built in client, configuraable via
its web interface.

You fill in your details at dyndns.org or another
service and it justs responds to DNS lookups with your
most recent IP address. The client will update the
dynamic dns service with your new IP address every
time it changes. You have to be careful though because
dyndns threaten to shut down your account if you don't
update every 30 days or so, so you have to do a manual
update (press the button on a smoothwall).

I use dyndns on a static IP address and I get mail and
web no problem. The only difference with a dynamic IP
is that you need a client to update their servers. The
DNS servers for you domain doesn't change, just the IP
address that they return. End users attempting to
access your site shouldn't see any difference.

Hope all is clear :)
