Redhat Linux 7.1 and qpopper

[Soprano Juan]

I've installed qpopper in a Redhat linux machine, I've setted up the pop3
inside the xinetd.d direcotory, and it starts perfectly, but when I try to
connect to the port 110 is like the daemon is not running, do I have to have
the IMAP RPM package from linux installed????,
Thanks.
