install problem

[unplug]

Hi all,

  I have successfully installed and configured the cyrus 2.0.12. 
However,
when I try to telnet the imap server, it displays below.

[root@mail cyrus-imapd-2.0.12]# telnet localhost imap
Trying 10.0.1.14...
Connected to localhost.localdomain.
Escape character is '^]'.
Connection closed by foreign host.

I make sure imap and pop is added to the /etc/services with the 
correct port.  I donno what's wrong and anyone can help??

Rgds,
unplug
