Email address fields

From shows the sender, To and Cc list visible recipients, Bcc hides some, Reply-To says where replies go and Return-Path is where bounces go. The delivery envelope is separate from these headers, which is why a message can reach someone not shown in To.

Verification is about the addresses you deliver to, not the visible headers. Check every address you put in To, Cc and Bcc.
