Do I have to anable to enable receipt of emails in my account?

You can't, not a provision in Yahoo email now.

If you send an email from Yahoo Mail and don't receive a failed delivery message, the email was delivered to your intended recipient's email system. But that doesn't guarantee the email was opened and/or read.

Yahoo Mail does not provide a "read/return receipt" feature.

To confirm that your recipient has received and/or read an important message, we suggest asking them to confirm receipt by sending you a reply.

Yahoo doesn't offer read receipts. There is no option for it in mail.

I want to forward something from my gmail account to my yahoo naccount. Google shows it as sent, but yahoo doesn't show it as received
