QMAIL port 25 and 110 are closed

Qmail installation went fine .But I was unable to connect to port 25 and 110.They were in closed state.When I tried to connect with telnet I got the “Connection refused” message.



# qmailctl stat
/service/qmail-send: up (pid 2219) 37 seconds
/service/qmail-send/log: up (pid 2311) 37 seconds
/service/qmail-smtpd: up (pid 2917) 1 seconds
/service/qmail-smtpd/log: up (pid 2723) 37 seconds
/service/qmail-pop3d: up (pid 2724) 1 seconds
/service/qmail-pop3d/log: up (pid 2989) 37 seconds

Looks good but when I try to connect on the mail server I got the connection problem.

]# telnet localhost 110
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused


# telnet localhost 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused



I have checked the logs for qmail-smtpd and qmail-pop3d and contains a lots of error lines like the following:
tcpserver: fatal: temporarily unable to figure out IP address for 0.0.0.0: file does not exist

I tried nmap

# nmap localhost

Here the ports 25 and 110 are closed

Finally I've got the solution from
QmailRocks

For the can't find IP address, fix this by "touch /etc/dnsrewrite"

I did the same "touch /etc/dnsrewrite" and a QMAIL RESTART.


# touch /etc/dnsrewrite
# qmailctl restart


It worked. Great.
