If you select ALL rules when you run manually, does the problematic
rule work or not?

Yes, when I enable all rules and running them manually, the
problematic rule works.


Then I would suspect you are attempting to exercise a rule that checks
for a string but within HTML-formatted e-mails. The string
"superfluous" is not the same as "superb/bfluous". While YOU
don't see the HTML formatting, especially because it toggles on and
off the bolding but affects no characters, your rule will still see
all the HTML tags. All HTML is plain text but e-mail clients will
attempt to render the HTML formatting which can mean some effects are
invisible to you.

You'll need to look at the raw source of the e-mail to see if the
string is actually in the one that you think your rule should trigger
on. If you are trying to trigger on spam words, and if they are
HTML-formatted e-mails, there are lots of ways of hiding those spam
words, like using abutting HTML tags, using tables, or other
formatting methods.
