My sendmail gets the local name from /etc/mail/local-host-names, which 
contains "donner.cannibals.org" and "cannibals.org."  I get the same 
result if I delete the "donner.cannibals.org" line from 
local-host-names, and if I use "Cwcannibals.org."

So I rebuilt sendmail.cf from scratch.  My sendmail.mc file is:


# $Id: cyrusv2.mc,v 1.4 2001/08/23 23:26:56 leg Exp $

divert(0)dnl
VERSIONID(`cyrus v2 sample configuartion')

OSTYPE(linux)
define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')
define(`confTO_IDENT',`0')

dnl setting cyrus as the trusted user will make it easier to pass
dnl Sendmail's safefile checks.  however, it means that someone with the
dnl "cyrus" password could easily become root.
dnl define(`confTRUSTED_USER', `cyrus')

define(`confLOCAL_MAILER', `cyrusv2')

dnl if you aren't using Sendmail 8.12, you might need to remove
dnl the following feature.
FEATURE(`preserve_local_plus_detail')
FEATURE(`nocanonify')
FEATURE(`always_add_domain')
MAILER(`cyrusv2')
MAILER(`local')
MAILER(`smtp')

MAILER_DEFINITIONS
Mcyrusv2,	P=[IPC], F=lsDFMnqA@/:|SmXz, E=\r\n,
	S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP, T=DNS/RFC822/X-Unix, 	 
A=FILE /var/imap/socket/lmtp

LOCAL_RULE_0
Rbb + $+ < @ $=w . >	$#cyrusv2 $: + $1


Among the several variations of the above that also don't work, was one 
in which I used FEATURE(`use_cw_file').

After sending email to testuser at cannibals.org, /var/log/maillog says:
