"returned to me"? Do you mean it bounced? Do you mean it had
root@something_or_other as the From: address? Do you mean something else?

These are good things. You might also verify that sendmail is working by
trying "telnet localhost 25".

This is the key thing I still don't understand. What host are you trying to
connect to here? The external address of your machine? Some other host on
your ISP's network? Something else?

Are you sure that the hosts you've telnet'ed to are running an MTA? Try
"telnet comarre.com 25" (my external FQDN) and see if you get a successful
response. You should. If not, try "telnet 63.198.182.124 25" and see if that
goes any better. In any case, tell us what you do get.

Try sending mail. You can also run sendmail in interactive mode, form the
command line, but I forget the details -- check the man page. Remember,
though: sendmail can connect only to hosts that are themselves running MTAs.
Not all hosts do. Only one of our hosts here ... the one that responds
externally as "comarre.com" ... runs an MTA, for example.

Can you send mail to other hosts on your LAN (if they run MTAs)? Or to your
mail server, if you have one?

Ahhh ... in general, there is no reason to expect to be able to telnet to
port 25 on the p-to-p address; there's no reason for an ISP to run an MTA
there. The smtp server is different; you should be able to telnet to its
port 25 ... whether sendmail is running or not.
So please try this one test one more time: "telnet 12.34.56.78 25",
replacing 12.34.56.78 with the actual IP address of your ISP's smtp server
(NOT its POP3 server, if they are different - Eudora uses both). Send a
follow-up quoting EXACTLY what you type and what the response is. Do the
same for the attempt to connect to my SMTP server, as instructed above.
These results may give us enough information to work with.
If you cannot make these connections with telnet, you do have a problem, but
it is not an MTA problem (because you are not using your MTA for these
tests). I don't honestly know what it is, but the exact errors may help me,
or someone else on the list, figure it out.
