How to change the "Reply to" of my Yahoo

Configuring your Yahoo! Mail Address
Yahoo! Mail enables you to change your reply-to address so you can receive your incoming e-mails using your new domain e-mail address.

For Example:
Your Yahoo! address is: mymail@yahoo.com
Your domain address is: juandelacruz@mydomain.com

If configured correctly, your reply-to address on your Yahoo! Mail will now be: juandelacruz@mydomain.com

Here's how to do it...

Step 1 - Switch to Yahoo! Classic - (see 'Options' on upper-right portion of your screen)

 
 
Step 2 - Select Mail Options

 
 
Step 3 - Select 'Accounts', then 'Add Account'

 
 
Step 4 - Type-in your new domain details, then 'Save Changes' when done
Note: You cannot click on the 'Set as default sending account' yet until this new e-mail address has been verified.

 
 
Step 5 - Go to your Yahoo Inbox and click the link to verify your new address!

Step 6 - Go back to Step 4, and click Set as default sending account to make your new e-mail your default 'From' or 'Reply-to' address
