Are you talking about removing the Received header of the MailScanner server so it doesn't look like the email went through it?  I would advise against doing that.

I would need to see one of the headers of email that has passed through this MailScanner server to better understand the problem.

If your MailScanner server is sending directly to the Internet, I would recommend putting a direct public IP on the server to make sure you get FCrDNS setup properly with a single PTR and matching A record matching the SMTP HELO.
