My machine is provided a fixed IP address from my ISP (dwarf.polaris.net)
which is only resolvable when my machine is connected. As a result, I use
the e-mail account my ISP provides (dwarf@polaris.net) and configure pine
to use that address in the From field. I use popclient (yes, I know, but
fetchmail doesn't do what I need) to retrieve my mail from my ISP dialup
account and read it from my machine when time permits.

I manage a separate account (on another server not connected with my ISP)
where I reply to the support questions from my book. The account on my
machine (debiansupport) that manages this task is configured to provide
the from address "debian-support@linuxpress.com", and uses the smtp server
provided by my publisher's ISP. This returns all replies to that account
where I can pop down that mail into the debiansupport account for reading
and answers. I believe that this process could be used to provide accounts
for multiple nodes on a LAN through a common provider, even using the
common provider's local mail server, as long as each node on the LAN has a
valid e-mail account on a server exterior to the LAN. If the gateway (the
node dialing up the ISP) is a perminant one, providing a relay server on
the gateway that could recieve mail for the various accounts on the LAN
should be a functional solution as well.

This is just my simplistic solution to the problem. I'm sure there are
other, more comprehensive solutions.
