This is obviously a very small network if they do not already have
established email service.
Install an Exchange server locally and make sure you have a modem on it.
With MS Exchange you can set it up to use a dial up connection in the event
that it needs to forward queued email. Your ISP has probably given you a
dialup profile as well as your DSL, so their SMTP relay services will be
configured to accept your email from whatever server is comes in on.
Setup your Exchange to use the DSL as its primary mail forwarding link. I
don't recall if there is a way to tell the server to automatically use the
modem if the primary link is down, you may have to manually switch it but it
will be very simple to do so.
Rather than setting up an Email server you may be better off using a SMTP
relay service and simply forwarding your email to your ISP for them to
route. You could do this easily with a PC which has both the DSL router and
a modem on it, and still get your redundency should the DSL go down. The
downside to this is that email needs to be stored locally on your users hard
drives. Having your own email server gives you that nice archive, and lets
you monitor what email comes and goes if need be. The downside to that is
needing to back it up and maintain it etc.
If you do decide to go with a local mail server, don't skimp on the
hardware. Buy yourself a decent server which has Raid5 capability and keep
a hot spare drive around. Make sure it has a decent backup system on it
too.
For right now I would just download a free SMTP relay agent from
Winfiles.com or Download.com etc, throw it on a PC, set all your mail
clients (built in email client in WWW browser) to use it, and give yourself
time to think about what you ultimately want.
