You are right, here are the missing informations:

--[ postconf -n

alias_database = hash:/cw/etc/postfix/aliases
alias_maps = hash:/cw/etc/postfix/aliases
allow_mail_to_commands = alias, forward, include
allow_mail_to_files = alias, forward, include
command_directory = /cw/sbin
config_directory = /cw/etc/postfix
daemon_directory = /cw/libexec/postfix
default_privs = cw-n
home_mailbox = Mailbox
mail_owner = cw
mailbox_command = /cw/bin/procmail -a "$EXTENSION"
message_size_limit = 30220000
mydestination = $myhostname, $mydomain, localhost.$mydomain,
cyrus.ecrc.de, /cw/etc/postfix/local-our-names
mydomain = de.cw.com
myhostname = supermail.de.cw.com
queue_directory = /var/spool/mqueue/postfix
recipient_delimiter = +
relay_domains = $mydestination,
hash:/cw/etc/postfix/access
relayhost = augias.de.cw.com
relocated_maps = hash:/cw/etc/postfix/relocated
setgid_group = cw-r
smtpd_recipient_restrictions =
permit_mynetworks, check_client_access
hash:/cw/etc/postfix/access,
           reject_unauth_destination
strict_rfc821_envelopes = yes
transport_maps = hash:/cw/etc/postfix/transport
virtual_alias_maps = hash:/cw/etc/postfix/virtual
--]

-snip /cw/etc/postfix/aliases:
testmuc: :include:/var/sendmail/www_aliases/var/user_include/testmuc
test.user: testmuc
-snip end

For localdelivery:
# cat /var/sendmail/www_aliases/var/user_include/testmuc
testmuc

(Postfix are right, the recipient in the include file loop back to the
user. But this is needed, because user are able to change the delivery
type with an webinterface.)
exampel to imapbox:
#cat /var/sendmail/www_aliases/var/user_include/testmuc
testmuccyrus.domain.de
