Connection Refused

[Allan T. Parreno]

Hello,

I encounter connection refused during communicating the imapd and pop3d, 
Here's some info,

[root at ja ~]# netstat -anp | grep 143
tcp        0      0 0.0.0.0:143                 0.0.0.0:*                   LISTEN      10097/cyrus-master

[root at ja ~]# ps -ef | grep cyrus-imap
cyrus    10097     1  0 Nov17 ?        00:00:00 /usr/lib/cyrus-imapd/cyrus-master -d

[root at ja ~]# telnet localhost 143
