Umm, nothing in Mailman is setUID. Mailmans permissions scheme
revolves around setGID (to allow non-privileged users to use Mailman,
even though this requires some cooperation with the sysadm in many
When mailman receives mail (via some alias-file pipe from your local
MTA (in most cases)), it checks that the gid of the spawned pipe is
running under some compiled in (real) gid, and then setgid()s to it's
own (effective) gid to allow Mailman to operate.
A similar scheme is used for changes done via the web interface.

Probably because using _one_ set of permission for all dirs Works (TM) :)
Seriously: You're probably right, and I think Mailman could be set up
with more restrictive permissions. This should be fixed, but hasn't
really been a top priority as it's not really a bug (and possibly
could be a cause of breakage for someone with ... "exotic"
configurations that Were Working Before They Upgraded (TM) :).
I'd like to address this after 1.0 is out the door.
