Installation is relatively simple. Follow these steps:

1)	Run `./configure`. This will create the Makefile and detect your system
	headers.

2)	If you are using procmail or something similar to deliver mail to a
	nonstandard mailbox location (e.g. $HOME/Mail/inbox) edit the file
	pop3d.h and define MAILSPOOLHOME appropriately.

3)	Run `make` to build. If all goes well, you can run `make install` to
	install. If you want to run in inetd mode, edit your inetd.conf file
	to point to the program (usually /usr/local/sbin/gnu-pop3d unless you
	specified something else with `./configure --prefix`), then restart
	inetd with a SIGHUP. If you are running in standalone, you'll need
	to create the appropriate symlinks in your /etc/rc.d hierarchy to start
	and stop the service in appropriate runlevels. You may also still need
	to edit inetd.conf to remove any lines that start other POP3 servers.
