I would like to implement a simple autoresponder type of response to all incoming emails to a specific mailbox. That I can do with the cPanel Autoresponder feature to reply to the email originator (the FROM address of the incoming email). But the part that I cannot determine how to do in cPanel is to also send a duplicate of that email autoresponder reply to one (or more) additional email addresses. If I could send the duplicate email autoresponder reply to say 'reply@domainname.com' then I could use the cPanel Email Filters interface to implement a filter to duplicate that autoreply to the one or more recipients that I would like to receive these duplicate autoresponder replies.
