go into your admin panel, Find Emails tab next to General.
Find where it says (Sender address for the messages from site:)
This is where you have to put in (no-reply@yourdomain.com),
below this you'll see (Email address for admin messages - not shown to users:)
Use any email address there.
I believe q2a is designed to read no-reply@yourdomain.com as emails send out from the system. I don't know how you'll fix this if you can not make your address as no-reply@yourdomain.com.
how are you hosting your site on your machine?. xampp, wamp, mamp.
