RFC 5322 3.6. (and AFAIK *all* its predecessors) marks the Date: header
as mandatory. sendmail used to forcibly add one if missing, I'm not sure
about other MTAs (and MSAs). I'ld recommend to try fixing the problem as
early and globally as possible, rather than on the last yard into *one
specific* mailbox.

Postfix is able to add the header, if you configure it do so. According
to its documentation "this may break DKIM signatures that cover
non-existent headers", so it's off by default.
(More in man 5 postconf - always_add_missing_headers.)
