I don't know how you're calling sendmail, but your example shows a RFC RFC 2822 header line. The SMTP protocol (RFC RFC 2821) actually considers those lines to be part of the body of the message and not really involved in delivery. The address used for delivery is normally called the envelope address, and that's passed on the sendmail command line.
