how to make E2K7 process Emails with bad x-sender

We are receiving emails from our ISP via POP account using 3rd party GFI
MailEssentials. This utility drops incoming mails in the pickup directory.

On some emails, for instance if an email could not be delivered, the
"x-sender" field holds just "MAILER-DAEMON". Exchange 2007 does not forward
this email due to invalid x-sender (if I change it to
MAILER-DAE***@dummy.com it works fine!).

How can I get Exchange to process emails with invalid (or certain invalid)
x-sender entries?

Any help is much appreciated!

Here's a tool that strips the x-headers;

You can also write your own agent to handle the headers;

whatever it is you are looking for, you should be targetting the transport
services; presumably with a transport agent.
