IMNSHO, the appropriate fix is to refuse these messages in the initial 
SMTP transaction.  RFC-2822, section 3.6 clearly states:

Any message without a DATE: and FROM: header is malformed and should be 
refused.  When I turned this on, the only legitimate messages that were 
bounced were from a stupid print-to-email feature on our HP 
printer/copiers.  I routed those through an MTA that added a DATE: 
header and all was fine.

YMMV
