It *does* listen there, just that it restricts itself to 127.0.0.1 ;-) 
That's a security measure that most distributions introduced years ago. 
F.i. I have been using Suse before CentOS and they do it the same. Suse 
controls the sendmail.cf in their /etc/SuSEconfig/sendmail file where you 
can specify to listen on external IP as well or to not touch the 
sendmail.cf at all, etc. I don't know if Red Hat-based systems have 
something similar, it's possible that you can put that configuration 
option in the /etc/sysconfig/sendmail file as well (once you know the 
syntax - is there documentation about all sysconfig options somewhere?).
