Sujet: [exim] From rewrite for incoming messages
Is there a safe way to rewrite From field for ALL incoming messages?  We are
having problems with Phishing where recipients only see the From field and
assume it has come from a trusted person and then click on the link or
download the file.
An example is as follows:

=======================================================
From: Sujit Choudhury <mailto:englishmailer@protonmail.com>
Date: Tue, 25 Jun 2019 at 12:22
Subject: Hello
To: mailto:j.baird@bbk.ac.uk <mailto:j.baird@bbk.ac.uk>
 
Are you in the office?
Please click on the link below:


============================================================================
=================================================
In this case j.baird thought, that the mail came from me, and like many
people reading their mails on phone, only the first part of the From field
is visible.
