That is how I set the DL definition.
I have tried this experiment on two different servers and managed to give the
wrong combination of versions.
What I actually have is one box with Fedora 22 and sendmail 8.15.1/8.14.4 and
the other with Centos 7.2.1511 and sendmail 8.14.7/8.13.3.
The results are the same on both boxes.
Further experiments show that running sendmail from the command line (eg
sendmail -bv noone(a)benparts.com.au) gives the correct result (delivery to
baduser) but when running as a normal daemon I get the reject (again on both
boxes).
Any ideas?
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)?
