Autoresponse from address error

Hi there, when I add two email addresses to the contact form (per the instructions “Enter one or more Email addresses (separated by comma) where mails should be delivered to)”), the “From:” header in the auto response email concatenates them into one string and it becomes useless – the recipient can’t reply to it.

I note that you have discussed adding the Reply-to header here which helps a bit but I need to change the From: header as well.

Any idea how to do that?

Thanks
