POP3 Again

There are some previous posts relate to POP3. Actually, I have the same problem, and I couldn't find the answer.
My system is Redhat 6.0, and I followed the instruction to enable POP3. But I still couldn't telnet to 110 port. It said "trying Trying
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host

Anything else I need to check up?
Here is the /etc/inetd.conf and /etc/services files
pop-3   stream  tcp     nowait  root    /usr/sbin/tcpd  ipop3d
pop-3           110/tcp                         # POP version 3
#pop-3          110/udp
pop             110/tcp                         # PostOffice V.3

Make sure that you have the file ipop3d in you /usr/sbin directory.
I also noticed in my services file I do not have the udp port commented out.
Also, try commencting out the pop  110/tcp line.

I am running RedHat 6.0 and my services file looks like:
pop-3    110/tcp     #POP version 3
pop-3    110/udp

I couldn't find ipop3d. I guess I need to insall imap. But I encounted problem when I installed imap.

I found the imap-4.5-3.src.rpm on my second cd-rom. when I run gnorpm to install it, it didn't give me any message when I press 'install' button. Then, I excuted 'rpm -i imap-4.5-3.src.rpm --allfiles', it returned to prompt immediately. I check 'rpm -q imap', it still said 'imap is not installed'.
Note: I'm root user.

Any idea? Thanks

You are trying to install the Source code and not the binary program. The "SRC" in the file name means it is the source. The source is not an executable program. It requires you to compile it and a whole lot of other stuff. There should be a file named "imap-4.5-3.rpm" This is the one you need to install.
