3.7.4 Spam Filters</A>
</H3>
<P>
This section provides some adjuncts to spam fighting tools; it
doesn't replace dedicated anti-spam tools such as SpamAssassin or
Spambayes.
<P>
<DL>
<DT><STRONG>bounce_matching_headers</STRONG></DT>
<DD>This variable contains header regular expressions, one per line,
and if any of a message's headers matches one of these patterns,
it will be held for moderation. The format is a colon separated
header and value, where the header is case insensitive and the
value is any valid Python regular expression. Lines that start
with # are ignored.
<P>
This variable can be used to catch known spammers by writing
regexps that match against <span class="mailheader">To:</span> or <span class="mailheader">Cc:</span>
lines, or known-bad <span class="mailheader">Message-ID:</span>s. Perhaps more useful
though are patterns that match headers added by spam detection
tools higher up in the tool chain. For example, you might
configure SpamAssassin to add an <span class="mailheader">X-Spam-Score:</span> header
with between zero and 5 stars depending on the spam score. Then
you can add a line to this variable like:
<P>
<dl><dd><pre class="verbatim">
X-Spam-Score: [*]{3,5}
</pre></dl>
<P>
This line will match from 3 to 5 stars in the value of this
field.
