Correct.  That would be site-wide.

I'd kind of rather not shut it down unless there isn't any other option. 
  We do hundreds of thousands of e-mail messages per day, and I'd rather 
not disrupt any of the other 100+ production lists on the server unless 
there is no other choice.

Mailman can do that, yes.  But it takes some more work, and you can't 
just blindly copy one mailman installation to another and then expect to 
start the second one up without a lot of additional work.

If you want to run multiple copies of Mailman on the same server, you 
really kind of need to do fresh installs for each additional copy.  This 
makes sure that all the paths are set correctly for each copy, including 
which different configuration file they are built to use by default, 
which different directory structures they're configured to use, etc....

It can be done, but it takes a bit more work.

If Skip wants to go that direction and doesn't have a machine of his own 
that he can use for this function, I think that the PSF has another 
couple of machines around that we could probably use for some short-term 

In that case, we'll just need to make sure that the appropriate accounts 
are in place, etc....  And one or more members of the postmaster team 
will probably need to be involved in helping set that stuff up, so 
there's going to be a bit of coordination to be done.

In this case, we're looking at USENET spam being gatewayed to e-mail, 
and I have no evidence that there has been any appreciable dropoff in 
USENET spam over the last couple of weeks.  So, this should still be a 
valid test going that direction.
