If the Yahoo inbox serves a single user, you must ignore all headers,
and deliver email to the local mailbox that corresponds to the user
in question.
Ideally, Yahoo prepends a "Return-Path:" header to the message, that would
the envelope sender address for the "MAIL FROM:" SMTP command. And the
statically defined local owner of the mailbox is the "RCPT TO:" address.
If the mailbox serves multiple local users, Yahoo must support multi-drop
mailboxes, by inserting envelope recipient information into suitable
headers (not "To:" or "Cc:", ...) of the message.
It sounds like:
- Yahoo likely does not support multi-drop mailboxes, and you
are in vain trying to simulate this. It is not possible.
OR
- The mailboxes are not multi-drop, but your software is misconfigured
to try and use them in that way. Don't.
