Comment 7 for bug 738263

Hi Ghada.

If I've understood things correctly, the point wasn't to hide the email address, but rather to enable messages to be delivered that would otherwise rightly be rejected (see the OP's description).

Imagine I'm using a Mahara installation running on mahara.example.org. My email address is <email address hidden> and I attempt to send a message to <email address hidden>. With the configuration described above, mahara.example.org will attempt to send a message claiming to be from <email address hidden>. If user2.net is properly configured, it will reject mahara.example.org's attempt at sending the email because mahara.example.org is not user1.org. If on the other hand mahara.example.org attempts to send an email from <email address hidden> with a Reply-to of <email address hidden>, the message should be accepted.
