These installation instructions are for specific operating systems
and software levels, but should at least serve as examples.
See the DRAC web page http://mail.cc.umanitoba.ca/drac/index.html
for the most current instructions.

DRAC is now incorporated into Debian Linux.  You don't need to
compile DRAC for this Linux version.  For more information, see:

	http://packages.debian.org/drac
	http://ftp.debian.org/debian/pool/main/d/drac/
	http://buildd.debian.org/build.php?arch=&pkg=drac
	http://bugs.debian.org/drac

You _must_ compile DRAC with the same version of the Berkeley db
package that was used to compile your copy of sendmail.  This may not
be the default version that is currently installed on your system.
One way to determine this is `strings /usr/lib/sendmail | grep -i
sleepy'.  Versions 2.x, 3.x, or 4.x of the Berkeley db package
(http://www.sleepycat.com/) is recommended, but version 1.85 will also
work.  The critical thing is to use the same version that was used to
compile sendmail.

1) Edit Makefile to suit your system.

   For Solaris:
	INSTALL = /usr/ucb/install
	EBIN = /usr/local/sbin
	MAN = /usr/local/man/man

   For NetBSD:

	CFLAGS = $(DEFS) -g -I/path/to/db/include
	LDLIBS = 
	TSTLIBS = -L. -ldrac
	RPCGENFLAGS = -C
	MANLIB = 3

   For FreeBSD 2.2.x:
	INSTALL = install

	LDLIBS = 
	TSTLIBS = -L. -ldrac
	RPCGENFLAGS = -C

   For Linux:
	INSTALL = install
	EBIN = /usr/local/sbin
	MAN = /usr/local/man/man
	DEFS = -DSOCK_RPC -DFCNTL_LOCK -DGETHOST -DDASH_C
	CC = <your compiler>
	RANLIB = :
	CFLAGS = $(DEFS) -g
	LDLIBS = -ldb
	TSTLIBS = -L. -ldrac
	RPCGENFLAGS = -C -I
	MANLIB = 3
	MANADM = 8

   For AIX:
	INSTALL = /usr/ucb/install
	EBIN = /usr/local/sbin
	MAN = /usr/local/man/man
	DEFS = -DD_BSD -DBSD_INCLUDES -DSOCK_RPC -DFCNTL_LOCK -DGETHOST -DDEBUG
	CC = <your compiler>
	RANLIB = :
	CFLAGS = $(DEFS) -g -I/path/to/db/include
	LDLIBS = -L/path/to/db/library -ldb
	TSTLIBS = -L. -ldrac
	RPCGENFLAGS = 
	MANLIB = 3
	MANADM = 1m

2) Compile the package:

	$ make

3) Install the server:

	# make install

4) Install the man pages:

	# make install-man

5) Install the startup script: For Solaris, customize dracd-setup and
   install it in /etc/init.d , with a link S78dracd in /etc/rc2.d .

6) Start the daemon:  For Solaris...

	# sh /etc/init.d/dracd-setup start

7) Modify POP/IMAP servers:  The dracauth() client function is suitable
   for mail servers that run a separate instance for each mail user.
   It should be called just after the user has been authenticated
   successfully.  Other mail servers will require a more complex
   interface.  See testing.c and dracauth.c for details.  The server
   hostname can be specified as "localhost" if it's running on the
   same machine, but it would be better as a run-time configuration
   parameter.  Here's a sample patch that works for qpopper:

8) Install the modified mail server:  For qpopper, it's `make' and
   `make install'.

9) Modify sendmail.cf:  For sendmail 8.9.0, add the following to
   your .mc file under LOCAL_CONFIG...

# dynamic relay authorization control map
Kdrac btree /etc/mail/dracd

   and the following under LOCAL_RULESETS...

SLocal_check_rcpt
# allow recent POP/IMAP mail clients to relay
R$*				$: $&{client_addr}
R$+				$: $(drac $1 $: ? $)
R?				$@ ?
R$+				$@ $#OK

  and then re-make the .cf file

10) Restart sendmail:  The SMTP and queue daemons will need to be
    restarted.
