Real domain name required for sender address

[John Patterson]

Hi,

Why do I get this message:

553 5.5.4 <[EMAIL PROTECTED]>... Real domain name required for sender address

even though this is commented out:


         <!--
         <mailet match="SenderInFakeDomain" class="ToProcessor">
            <processor> spam </processor>
         </mailet>
         -->

Thanks,

John.
