You could do this with seive.
But it seems like an odd rejection. I am sure I am not the only person who
fires notes to themselves via email with no subject.

Did you mean:
1) No Subject: line. For this case you need an external content
filter (Milter, smtpd_proxy_filter, filter).
2) A Subject: line without text. Postfix can match this with
header_checks
Hello list,
