[CentOS] cyrus-imapd - unable to connect to POP3

This is the first time I am using cyrus-imapd package.

I am unable to retrieve messages (pop3).  At first, I had not entered
the cyrus-master in /etc/hosts.allow and was getting connection refused.
After adding the entry I am able to connect to port 110 but for some
reason the pop3 server is failing the password authentication (see
below).  With the same userid/passwd I am able to ssh into the server.

What other configuration am I missing.

        $ telnet 192.168.1.21 110
        Trying 192.168.1.21...
        Connected to 192.168.1.21.
        Escape character is '^]'.
