<p>I'm using Parsley IoC in my current Flex project. So I'd like to embed the container configuration XML onto the result SWF. </p>

<p>How could I load embedded XML file into action script XML object?</p>

I think the problem is that sendmail (your process) is talking to the local sendmail daemon.   The local sendmail daemon thinks that because it is website.com, it should know how to deliver the email.  Unfortunately, the actual address in the to field does not exist on the web server and thus it dumps it in the "catchall" mail box.  You should talk to your ISP and have them update their sendmail configuration so that mail addressed to ...@website.com gets forward to the mail exchanger instead of being handled locally.
