Guess what I did today? I sent an email to noreply@speakinginbytes.com. Why did I send an email to a noreply@{domain} address? And why to my own domain? Because as I was flying through my email using all of my fancy gmail shortcuts I opened an email, pressed r to reply typed up a response pressed tab and return and let it fly. Only then did realize that I sent it to my own domain. What would've been really handy in this situation would be a way to automatically change the from address in emails that already contain the requestor's email address.
A quick Google search will turn up this great post by the WP Ninjas (the guys who make Ninja Forms) about dynamically changing the email address. This is actually a really great solution because you can specify exactly which fields you want to use for the name & email address as well as which forms you want to apply this to. The only down side is that it isn't plug & play – and I like plug and play. That way if I ever create another form or modify my form by adding or deleting fields it will still work.
