Setting up a POP3 Server under NEXTSTEP 3.3

To set up a POP server, you need to perform these simple steps (as root):

1. Install the following program in /usr/etc/popper:

(Source: ).

It's 4-way fat, so it should work on your machine.

2a. Replace the current (obsolete) entry for the pop service in /etc/services with the following two:

pop2		109/tcp
pop 		110/tcp postoffice

2b. Then reload NetInfo's services list by doing:

# niload services . </etc/services

3a. Add this entry to /etc/inetd.conf to start the daemon whenever you connect to the pop port:

pop	stream	tcp	nowait	root	/usr/etc/popper popper

3b. Make inetd notice it by sending ita a "hangup" signal:

# ps cax | grep inetd
  251 ?  SW    0:00 inetd
# kill -HUP 251

You're done. Try connecting to your machines POP port to test it:

% telnet localhost pop

It should respond with:

+OK UCB Pop server (version 1.831beta) at <hostname> starting.

Type "quit" to sign off, it's working fine. If you don't see that prompt, verify that pop indeed has been defined in services and /etc/inetd.conf:

% nidump services . | grep pop
pop     110/tcp postoffice
pop2    109/tcp
% grep pop /etc/inetd.conf
pop     stream  tcp     nowait  root    /usr/etc/popper popper

Good luck,
