fail to telnet localhost 106

Hi folks,

Ubuntu 7.04 server amd64

On running;

$ telnet localhost 106

Code:

Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

$ netstat -an | grep 106
$ sudo netstat -an | grep 106
both no printout

Pls advise where shall I check and how to fix the problem. TIA

P.S.
1)
confirmed with ISP port 106 is open

2)
I'm adding "change password" plugin on SquirrelMail. After installing poppassd on repo I tested it whether works according to /usr/local/squirrelmail/www/plugins/change_pass/INSTALL

Code:

Be sure to test and make certain your poppass daemon is working properly.
To test, try telneting into the daemon and changing a password:

$ telnet localhost 106
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
200 poppassd v1.8.1 hello, who are you?
user <username>
200 Your password please.
pass <oldpassword>
200 Your new password please.
newpass <newpassword>
200 Password changed, thank-you.
quit
200 Bye.
Connection closed by foreign host.

B.R.

POPPASSD(8)															       POPPASSD(8)

NAME

       poppassd - Password change server for Eudora and NUPOP mail clients

DESCRIPTION

       poppassd  runs  from  inetd  and listens on TCP port 106 by default.  Its sole purpose in life is to engage in short FTP-like conversations
       from client applications and execute (or deny) remote password changes via the PAM facilities configured in /etc/pam.d/poppassd.  The  con-
       versation looks something like this:

	      200 poppassd v1.8.4 hello, who are you?
	      user adconrad
	      200 Your password please.
	      pass foo
	      200 Your new password please.
	      newpass bar
	      200 Password changed, thank-you.
	      quit
	      200 Bye.

       As can be seen from the example above, unencrypted passwords are transmitted over the network.  Because of this, it is recommended that you
       use this daemon only for local loopback password changing (for instance, from Perl, Python, or PHP web applications on the same server) and
       block all non-local access to port 106, either via tcpwrappers (/etc/hosts.deny) or with appropriate firewall rules.

       If  sending  unencrypted  passwords  over  the  wire  doesn't  bug  you	terribly much (as in the case of an ISP with hundreds of POP3 mail
       accounts), this daemon can provide a simple way for some of your clients (those running mail clients that actually support  this  protocol)
       to easily change their passwords.

FILES

       /etc/pam.d/poppassd
	      Contains	the  PAM  configuration for poppassd.  By default on Debian, it merely includes the common-auth and common-password files,
	      which should work in most cases.	If this doesn't cut it for your site, tailor to suit.
