Hello!

In the new Yahoo Mail (web desktop), the sender's actual email address does not show by default - only their name. After hovering over the sender's name, if the email address is too long for the dialogue box it will cut off with a " ... ". When this happens, the full email address becomes completely inaccessible. This is problematic with spam and fraudulent messages, where sometimes the best red flag that a message isn't genuine is seeing the actual email address. Even if I hit 'reply' and attempt to look at the recipients address that way, there is no way to access the full email address beyond the sender's name in the "To" box.

At minimum, PLEASE don't cut off the mail address even if it's long.
A maximum, please show the sender's full email address by default. This can make it quick and easy to verify the sender.
Please also make it easy to access the recipient's full email in the "To" box.

Thank you,
Ryan
