First, you need to look at logs. Mailman's vette log will have a message
like
Message discarded, msgid: ...'
list: ...,
handler: ...
for each discarded message. In the case of header_filter_rules, the
handler will be SpamDetect.
Note that if you change the action to Hold,the vette log message will be
<listname> post from <sender> held, message-id=<...>: <reason>
and if your Mailman is 2.1.26, <reason> will tell you which regexp
matched. Prior to 2.1.26 it just says "message matched a filter rule"

You should be aware that these regexps are matched case-insensitively.
You can't make them be case-sensitive.

For bounce_matching_headers it appears you just have the defaults which
probably never match as they are over 15 years old, and these result in
Holds, not Discards.

If these are in discard_these_nonmembers, the handler will be Moderate.

How are you seeing these things if the messages are discarded?
