Yes, they are being rewritten. But, I just eliminated MailScanner as the
culprit. Something in sendmail is the only thing left to check.

I had several possible culprits and only posted when it was down to
sendmail and MailScanner. I just assumed that a vanilla install of
sendmail couldn't be the problem.

Sorry to bother everyone.
