<h2>Description</h2>

<p>ADDRESSMODIFYCODE may be used to define Perl expressions to
apply to addresses in message headers during conversion.
</p>
<p>When defining the expressions, the mail address will be in
the <b><tt>$_</tt></b> variable.  The value of <b><tt>$_</tt></b>
after all expressions are evaluated is the address MHonArc will
print.
</p>
<table border=0 cellpadding=4>
<tr valign=top>
<td><a name="note1"><strong>NOTE</strong></a></td>
<td><p>ADDRESSMODIFYCODE only affects the display text of the
address.  If <a href="mailto.html">MAILTO</a> is active, the
URL of the link is <b>NOT</b> affected by ADDRESSMODIFYCODE.
<a href="mailtourl.html">MAILTOURL</a> can be used to modify the
URL.

<h2>Examples</h2>

<p>ADDRESSMODIFYCODE main use is to obfuscate addresses,
or hide them entirely, to
prevent spam address harvesters from getting user addresses from
MHonArc archives.  Here is an example that performs a ROT13 to
provide some simple obfuscation:
</p>
<pre>
&lt;AddressModifyCode&gt;
tr/A-Za-z/N-ZA-Mn-za-m/;
&lt;/AddressModifyCode&gt;
</pre>
<p>However, this may not be enough since an intelligent harvester
may try a ROT13.  To completely hide the address, do something like
this:
</p>
<pre>
&lt;AddressModifyCode&gt;
$_ = 'address@hidden';
&lt;/AddressModifyCode&gt;
</pre>
<p>You cannot rely on ADDRESSMODIFYCODE alone to
hide/obfuscate addresses (see <a href="#note1">NOTE</a> above).
Also look at the <a href="spammode.html">SPAMMODE</a> if you are
interested in fighting address harvesting.
