8 <h1>HOWTO - Using the RBL</h1>
10 <p>The MAPS (Mail Abuse Protection System) RBL (Realtime Blackhole
11 List) is a means of identifying hosts that have been associated
12 with the sending of spam mail. A full description of the
13 service and the technology and ethics behind it can be found at
14 <a href="http://maps.vix.com/rbl/"><tt>http://maps.vix.com/rbl/</tt></a>
15 along with more general mail policy information at
16 <a href="http://maps.vix.com/"><tt>http://maps.vix.com/</tt></a>.</p>
18 <p>Exim can use the MAPS RBL and/or any other similarly defined
19 service (ie you could make your own additional maps as well).
20 To use exim for this you need to be running version 1.80 or
23 <p>This documentation is for versions of exim before version 3.00,
24 which are now considered obsolete. The current information can be
25 found in the <a href="rbl.html">most recent version of this
28 <h2>RBL Configuration Options</h2>
30 <p>These are fully detailed in the <a href="../exim-html-3.00/doc/html/spec.html"
31 target="_top">Exim Specification Document</a>. The specific
33 href="../exim-html-3.00/doc/html/spec_39.html#SEC708">here</a> and the rbl directives
34 are documented starting <a href="../exim-html-3.00/doc/html/spec_10.html#SEC283">here</a></p>
36 <p>The 2 standard RBL configurations are:-</p>
39 <li>Use RBL to add a <tt>X-RBL-Warning:</tt> header which can be
40 used by users for filtering
42 rbl_domains = rbl.maps.vix.com
43 no_rbl_reject_recipients
48 <li>Use the RBL to reject mail from barred machines
50 rbl_domains = rbl.maps.vix.com
55 <p>In both cases machines can be explicitly removed from RBL
56 control by adding their network addresses to the
57 <tt>rbl_except_nets</tt> list.</p>
59 <p>The information to do more complicated manipulations can be
60 found in the specification document and is outside the scope of
