I don't think I understand. Where does anyone ever have to see
"entropie.net"? Your ISP gives you an address which resolves to
<mumble>.example.com; you set sendmail to HELO as example.com.
No other name seems relevant to this; we're talking about envelope senders,
not what might or might not be in your From line.
