I do know how to set a reply to header. The reply to header is only required when the reply should be sent to a different address. This does not apply to Contact. The reply should always be sent to the individual whom enter their email address in the contact form. Adding this extra field, which nearly everyone will not understand, would not be a good addition to Contact.
I am under the impression that the Ultimate Branding plugin you are using was setting reply to field via a filter before sending the email.
The code I had you comment out was added to prevent other plugins from messing with email. So, I was curious is removing that code would allow Ultimate Branding to add the reply to field.
Maybe my understanding is not correct… Is Ultimate Branding supposed to be adding the reply to field or not? Honestly, I am a little confused as to why you would want to override the user supplied from address so all replies are sent to you instead of the user supplied email.
