Yes, it ends up at bar@<contents of /etc/mailname>.

I have the exact same setup with Postfix on another machine (satellite
system/nullmailer.)  Here's some data:

heinrich:~# cat /etc/mailname
complete.org
heinrich:~# grep complete.org /etc/postfix/main.cf
myhostname = heinrich.complete.org
mydestination = heinrich.complete.org, localhost, heinrich
 [ snip ]
heinrich:~# grep mailname /etc/postfix/main.cf
# is /etc/mailname.
#myorigin = /etc/mailname
myorigin = /etc/mailname
heinrich:~# echo foo | sendmail jgoerzen
heinrich:~# tail -n1 /var/log/mail.log

OK, I thought that this question may cause confusion with other setups,
though, too.  Though I admit I haven't looked at the debconf code at
all.
