<p dir="auto">What happened was that yyy scheduled a meeting. In Outlook (and some other calendars), there's an option to reply to the people in the meeting by making a comment in the calendar. Apparently Exchange sends the comment out with the <code>From</code> of the original calendar creator, but the <code>Sender</code> of the person who made the comment.</p>
<p dir="auto">But it got me to wondering whether there was a way to show the sender in the from line when they were different. Mainly that would show up for mailing lists:</p>
<pre style=":not([style]){background-color:#E4E4E4; border:thin solid gray; margin-left:15px; margin-right:15px; overflow:auto; padding:5px}"><code>From: J Smith (sent by mailing list)
</code></pre>

<p dir="auto">To be honest, I've never really looked into the <code>Sender</code> header. Although the above seems sensible then based on my emails I'm not sure it would always work well. It seems I've got some weird Sender headers in some messages and quite a few which have a Sender header which is identical to the From address (which is incorrect behavior according to the RFC).</p>
<p dir="auto">Your suggestion makes sense, but I don't see Apple Mail doing it. Maybe some other email clients handle it well?</p>
<p dir="auto">(Low level, it's possible to force MailMate to show this header, but it's not possible to prevent it from being shown when it's not unique.)</p>
