Final-Recipient: rfc822;&lt;some@email.com&gt;<br />

550 Authentication turned on in your email client

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.
