I've setup a form that sends a mail to an account that auto-responds to the sender. Mail are being sent from the site but the autoresponder isn't working because it semms to repliy to the return-path header of the mail, which is set in my php.ini in Windows Server 2003.
I've tried setting
Reply-to: <[EmailAddress]> as an additional Header but it doesn't change the Return-Path. Is there a way to set the Return-Path in Contact Form 7?
