There's a wonderful utility called install-sendmail. Look for it at
freshmeat.

It asks a bunch of rude questions and then spits out the appropriate
sendmail config files. Just install them, restart sendmail and you're
done. :-)

=>Greg,
=>      Sendmail needs a domain name so it can tell other systems who is
=>sending the mail.  One way to set it up for a home system is to give
=>it a made up name, and then tell it to masquerade as your ISP.  This
=>will not work in your case because of the open relay problem.  But I
=>am not sure how you can get around it because a lot of systems that
=>filter out open relays also filter out dialup IP's, as well as
=>systems that don't have valid DNS records.  With no MX record for your
=>system, your mail will probably get rejected by the same systems that
=>reject mail from your ISP.
=>      One thing you may be able to do is to set up sendmail to send
=>messages out using the uucp through the same link as you get your
=>mail.  It depends on the system you get your mail from.  Will they
=>accept mail from you that way?  Is that system an open relay, or
=>will mail from them be acceptable?
=>      Maybe someone else on the list know of another way around the
=>problem.  Changing to another mail program will not help unless you
=>can get someone to relay outgoing mail for you that is not an open
=>relay...
