IIRC, this poster is in a *BSD jail() environment, without the
root password -- which I think means that this jail is dedicated to
him. He got the guy with root password to change all these files,
but in this circumstance I don't think that worked quite the way they
Assuming I am correct, then changing the group writership of this
file shouldn't pose a greatly increased security risk, although he
should be aware that anyone who can get into the mailman group on the
bare machine would then be able to access and modify the files from
outside the jail.
Unfortunately, when you're trying to run something like this in a
chroot() or jail() environment that doesn't completely and totally
simulate a full virtual machine where you can have complete root
access to your entire "system", things tend to get a bit strange.
I think relatively few mailman admins are in this kind of
environment -- most either own the entire machine or they use list
hosting facilities provided by others, and not many are between these
This also means that there are few experienced mailman admins who
can answer questions about chroot()/jail() strangeness based on prior
experience, or who can then put that kind of information into the
documentation, FAQ, etc....
