Hello. That is possible, the email is sent to whoever is in the RCPT-TO
command of the SMTP transaction.

The sender does this:

<open connection to your MX>
HELO someclient.example.org
MAIL-FROM: sender@example.org
RCPT-TO: jeremy@example.com
DATA
From: someuser@example.org
To: kristin@example.com
Subject: this is a spam message

Hello kristin!
.
QUIT
<disconnect>

The sender *feeds* the To-header into the submission, but actually sends
the mail to a different user.

The "To:" header is just a decoration.
