I would be inclined to use a different regexp. something like

/^\s*(\(?no subject\)?)?\s*$/i

to catch subjects like 'no subject' and '(no subject)' too.

Also, this rule only hits on messages with a Subject: header. There is a
standard rule MISSING_SUBJECT for no Subject: header at all.

This rule is defined in 20_head_tests.cf as

header __HAS_SUBJECT		exists:Subject
meta MISSING_SUBJECT		!__HAS_SUBJECT
