One sender is sending emails with headers such as:
X-Script/function: OrderConfirmationEmailService
and
X-Script/function: /Object/UserEmail.cfc/sendUserEmail

This results in errors:
letters.ParseEmail: cannot read message: malformed MIME header line: X-Script/function: OrderConfirmationEmailService

It would be nice if we could have the option to ignore malformed headers that aren't critical to extracting data from the email.
