Change your reply-to address in Yahoo Mail
By default, when you send someone an email and they click Reply, the email address you sent the message from will get their reply. You can change this behavior so that when they reply, a different address will get their message. You can change the reply-to address to another email address already attached to your Yahoo Mail or you can add a new one.

Add a new "Send-only" address to your Yahoo Mail account, and then you can use the steps above to change the reply-to address.
