Perhaps surprisingly the answers are in the sendmail(1) manpage. :-)
Just one fact to keep in mind, that may not be covered. The "Return-Path"
header is NOT a sender-side interface. It gets deleted when messages
are queued for delivery, and is only put back on final delivery by the
destination system delivering the message to the recipient's mailbox.
The sendmail options you're looking for are:
-i - Leading "." is just text
-t - Read the recipient list from the message headers
-f - Specify the envelope sender.
-N - "never" or one or more of delay, failure, success
The "-r" option is a legacy form of the equivalent "-f" option.
