This is today's phishing email. I get a few of these every week. It is useful to set Mail prefs in "Viewing" to UNcheck the "Use Smart Addresses" box, which will then always show the actual name and email address attached to the "From" address.
I've been wondering since July, why even with
"Use Smart Addresses" unchecked, Mail was not
displaying the "From" addresses in the manner
that is displayed in your screenshot.
I would still be wondering, but, apparently,
I didn't toggle the checkbox on/off enough.
Today it relented and is displaying like yours.
