Autoresponse: wrong email address

[humanism]

You recently sent a message to this IHEU email address. The message could not 
be delivered, because the email address has been changed or does not exist. 
This is a permanent error.

Please re-send your message to one of the addresses listed at 
http://www.iheu.org/email.html.

If you did not send email to this email address, it means that our server 
received a message (probably spam) forged to appear to be from your address. 
This is a common problem and you can safely ignore this message.

Sorry for any inconvenience. We had to change all our email addresses because 
our old email addresses were being spammed beyond the capacity of our 
mailboxes, spam filters and people's time to sort wheat from chaff.

This message was generated automatically. For a human response, please use one 
of the email addresses at http://www.iheu.org/email.html. Thank you.
