For the sake of security- Yahoo must stop hiding the senders email.
Hello, For the sake of security- Yahoo must stop hiding the senders email address when viewing emails. Seeing the actual email address helps users like myself confirm if an email is a spoof address. The only way to see the actual senders address is for me to click 'reply' so that the senders address then shows like this- support@prime.com info@jobhotel.be. This email spoofed itself to be from Amazon Prime but the real address shows @jobhotel.be. So your current yahoo mail design is going to get a lot of people scammed I hope you realize.

Hi Michael, you can see the sender's email address two ways.
1. From your Inbox, before opening the email, if you hover over the sender's name, you will see the full email address.
2. If you open the email, again, if you hover over the sender's name, you can see the full email address.
Hope this helps!
