<p>The x-original-to is unfortunately not a real standard, so my guess is that the software receiving mail for the aquamacs list add the header (understandable, if fronted by a normal SMTP server) the mailing list software doesn’t strip the header before re-sending it to the list members, and your mail server doesn’t add/overwrite the header (it might use some other header to indicate the original to address of the email).</p>

<p>Alan created a <a href="http://freron.lighthouseapp.com/projects/58672/tickets/202">ticket</a> with the full headers.</p>
<p>Here are the most relevant ones:</p>

<p>According to Alan the subscribed address is <code>alan.schmitt@polytechnique.org</code>. This</p>
<p>The only header containing the correct address is a <code>Received</code> header. I guess the problem is related to <code>*.inria.fr</code> which does not add a <code>X-Original-To</code> header.</p>
<p>The mailing list software, by the way, is exactly the same as used on this mailing list:</p>
<pre><code>X-Mailman-Version: 2.1.12
</code></pre>
<p>I'm not sure what to do about this other than making the mailing list address derivation an optional feature in the preferences. I could perhaps also never trust an <code>X-Original-To</code> header which has been added before a <code>Delivered-To</code> header.</p>
