I’ve set up a simple contact form and also setup the auto reply to email as well. i.e. once the user submits the form they receive a confirmation email as well as the ‘Your form has been submitted’ on the page.
I’ve ran a few tests and the auto reply email to the users email keep coming back as ‘unknown sender’.
My fear is they will end up in junk mail.
Is there a way to enable this feature to display an email address?
Try with CF7: http://wordpress.org/plugins/contact-form-7/
Afaik, the current built-in contact form does not have that feature: https://kriesi.at/support/topic/contact-form-email-field-as-sender-from/
