Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically.
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.)
Thanks Jiri, this is the best solution.
