This directive should be sufficient. Not sure how about its order in
'sendmail.mc', usually I give it somewhere towards the end of the file.
Local user ('baduser' here) must, of course, exist - but it may be
an alias to real name.
It is not possible, that your /etc/mail/{mailertable,virtusertable}
values cause this mail rejecting?
You test it from commandline as root or as ordinary user?
What about selinux?
What You have in your /var/log/maillog and /var/log/messages (or in
journald log, when you are using this bullshit advancement)?
