This seems to hint that the qmail program doesn't want to be run by the 
root user. Running as the root user is known to cause some obscure 
security risks where privilege separation isn't in place (although it 
seems like a fairly crude workaround for a program like qmail). Postfix 
does privilege separation and doesn't trust the contents of its own 
mailqueues, so it should work when run as root on that system.
