I hate to keep harping about sendmail.cw/known-host-names, but you haven't
given me an answer. What's happening is sendmail thinks the recipient
nathan@the-arcanum.org needs to be delivered via the esmtp mailer, i.e.
not local delivery. Sendmail doesn't think this host is receiving mail
for the-arcanum.org.
What's in sendmail.cw/known-host-names and sendmail.mc?
