What have I missed here.

IMO what You want is configured by defining macro "LUSER_RELAY", as: define(`LUSER_RELAY', `local:baduser') And, it seems as You are using old sendmail versions with F22: v8.14.7 was semewhere in F18/F19, and sendmail v8.13.3 in Fedora 4 (ten years ago!). It has any reason?

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)?
