You can remove/ignore that. Its the sendmail '-f' option. There are 2 From
headers: the envelope and the message From that is visible in the email
itself. The envelope 'From' is typically not visible to email clients. The
envelope From is usually a system generated thing. So it is sometimes useful
to force this to something else. For example, in a shared hosting environment
where there are many domains on the same server.
