Display from

Reason: "Friendly Guy" is the display name and "[email protected]" is the address shown in the From: header (e.g. From: "Friendly Guy" <[email protected]>). That header is easily spoofed. For verification, check the Return-Path/envelope-from and Received headers and use SPF/DKIM/DMARC to detect spoofing.
