That statement is not correct nowadays as UNIX permissions aren't all 
any longer. There are tools like AppArmor and in your case with Fedora 
there is SELinux preventing even actions by root user.

Make sure the SELinux context fits. "/home/vmail" and the subfolder 
"Maildir" has to be SELinux labeled correctly.
