I use Gmail. When it displays an email from someone, it puts their name at the top. Sometimes, this is totally wrong, eg:
The person has "jo" in their email, and signs the email "Jo", but Google thinks they're called "Patricia". Their email isn't a gmail account.
Where does this data come from? It's annoying as it's all too easy to write "Hi Patricia..." in the reply and then sometimes people get annoyed saying "My name's not Patricia, it's Jo!".
Can this functionality be switched off?
EDIT - on examining the original text of the email, I can see this in the headers: Note the first in particular.
From: Patricia Wood <email@example.com> Content-type: text/plain; charset=utf-8 Content-transfer-encoding: quoted-printable MIME-version: 1.0 (1.0) Date: Mon, 19 Feb 2018 17:18:21 +0000 Subject: Three Little Birds Message-id: <E165616C-BE55-4E16-9298-68BD219693E5@xxxxxx.com> To: firstname.lastname@example.org X-Mailer: iPad Mail (15D60) X-Original-Sender: email@example.com
So, I'm guessing the "Patricia Wood" bit is something that is added by their email client?
