I'm glad you got this problem fixed. I'm also relieved it was not a bug
in the security policy after all, we did try pretty hard to make sure
the policy shipped without problems but our testing centered around new
installations and didn't take into account copying in foreign files.
This sounds like something that needs documentation.
restorecon is the right tool to relabel files to their defaults in
specific directories. fixfiles would have relabeled the entire system
and is not generally recommended.
It may have helped if you had been the user mailman when you copied the
files as opposed to root, but there are many issues that impinge. Was
the operation a move or a copy? Did destination file previously exist?
Would you have had permission as mailman to read the files? etc. Rather
than enumeration all the possible considerations when dealing with files
and directories under the protection of SELinux the most expedient path
is to copy the files and relabel the files using restorecon, just as you
