If you turn of bounce_processing (the only way to turn off automatic
removal other than perhaps setting bounce_you_are_disabled_warnings to a
very large number), Mailman will ignore all bounces of posts. It won't
notify the admin or the user, and if the bouncing user's ISP is
compliant, it won't notify the poster either as all bounce notifications
should be returned to the envelope sender of the delivered post which is
Mailman and not the poster.

As long as the spam doesn't spoof a list member address.

Controlling what posts reach the list will not have any effect on posts
which are blocked by recipient ISPs for DMARC or other policy reasons
except perhaps indirectly by affecting the reputation of the Mailman
server, but if I understand correctly, your list is one of many on a
shared host, so you are in some sense at the mercy of others.
