Compilation & Installation Instructions
---------------------------------------

For most people, the usual:

./configure
make

su(do)
make install

is enough. This installs dyn-host-filter under /usr/local.

Some GNU/Linux-distribution users may prefer to run: ./configure --prefix=/usr instead.
This will install dyn-host-filter under /usr.

See ./configure --help for a list of all available configure options.


Running
-------

1) You should edit your /etc/dhf.conf according to your needs and spam-policy.
You can safely delete the lines where the values correspond to the default ones. 


2) Make sure that you have the ucspi-tcp collection (http://cr.yp.to/ucspi-tcp.html) 
   with rblsmtpd installed.


3) dyn-host-filter should be run from tcpserver with both -h and -p enabled. 
   An example tcpserver line may look like this:
   /usr/bin/tcpserver -x/etc/tcp.smtp.cdb -h -p -u 201 -g 200 0 smtp dyn-host-filter rblsmtpd /var/qmail/bin/qmail-smtpd

  Finally the tcprules database (/etc/tcp.smtp.cdb) must contain a RBLSMTPD="" for each entry to be passed (like the line bellow):
  10.0.0.2:allow,RELAYCLIENT="",RBLSMTPD=""

  N.B. Make sure that the tcpserver process (usually run as qmaild) has 
  the necessary access to: /etc/dhf.conf (read) and /var/log/dhf.log (write)!!!
