It's most likely that it's a mail relaying problem, the first thing to
check would be whether there is an entry in the hosts, nis or dns for
whichever machine you're running eudora on, the maillog file should also
indicate if this is a problem (sendmail will only relay mail from hosts it
can resolve the ip addresses of) if it's not that then you should try
posting the section of maillog which shows a client trying to post.
Checking out the README file in /usr/lib/sendmail-cf would probably be a
good idea as well.
