Create service

Create directory service with:

/var/qmail/bin/qmail-pop3d-conf /var/qmail/bin/auth_pop qmaill /var/qmail/service/pop3d

Define access

Add to /var/qmail/service/pop3d/tcp file the list of allowed IP's to connect. If any IP can connect to POP, create tcp with:

:allow

And if you want to restrict access for a set of IP addresses, put something like:

172.16.1.24:allow 192.168.:allow

You can also add IP's with add-client command:

./add-client 172.16.1.24 192.168.

Now make the binary file in order to qmail(tcpserver) recognize the change:

cd /var/qmail/service/pop3d
make

Enable service

Activate the service:

ln -s /var/qmail/service/pop3d /service

LOG

Activate extended log level:

echo "3"> /service/pop3d/env/POP3_LOGLEVEL

Test

Check status:

svstat /service/pop3d /service/pop3d/log

If all is OK youll get something like:

/service/pop3d: up (pid 6345) 6 seconds
/service/pop3d/log: up (pid 6347) 6 seconds

Check the logs:

tail -f /service/pop3d/log/main/current
