In the situation you describe, the subject is blank and the MUA reading
the mail is providing the "(no subject)" message.

This one is good for picking up things like "Re: No Subject" that might
be produced in a reply. Assuming you are putting these in
header_filter_rules, you don't need [Ss] etc. as the pattern match is
set to ignore case.
>[Ss]ubject: [Nn]o [Ss]ubject
This is redundant if you have the previous one.

Have you tried
