Because it will be connecting on the IPv6 address ::1 - which is also localhost.
Look in /etc/hosts and you will see:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
There is a bug in the centos default exim config file, the line:
hostlist relay_from_hosts = 127.0.0.1
should read:
hostlist relay_from_hosts = localhost
I have had a friend also fall into this hole. I will raise this with redhat and
get it fixed.
