Inetd is refusing the connection. Most sysadmins set inetd to refuse all
connections by default, then accept connections for specific services
from specific hosts/networks.

Take a look at /etc/hosts.deny. It probably says ALL:ALL, which denies
all connections. It it doesn't you should seriously consider adding that

Your /etc/hosts.allow file should specify what services you want to
accept connections, and where you will allow those connecstions to
originate. In this case, you probably just want your LAN users to have
access to pop3:

ipop3d : LOCAL 192.168.1.

That assumes you use 192.168.1.* for your local IP addresses.

You will also need to allow them to use your box for outgoing SMTP. This
is a sendmail function you can change by editing /etc/mail/access
according to /usr/doc/sendmail-xxx/README.cf.
