First, a warning: This relies on internal Mailman directory
structures, which is liable to change in future versions (e.g. to
avoid collision problems with several lists having the same
(localpart) name when housing multiple mail domains in one Mailman
installation).

Next, wouldn't checking for the existence of config.db be better?  The
Mailman code goes to great lengths to ensure that a valid config.db is
present at all times -- I'm not sure (haven't checked) that the same
is true for listinfo.html.  Besides, internal parts of Mailman (like
the listinfo overview page) uses existance of config.db as a (first)
test of whether the list is present or not.

There also is a potential problem with this configuration that ought
to be mentioned: If you are housing several mail domains
(e.g. foo.domain and bar.domain) within the same Mailman installation,
creating a list which should only be reachable at <gazonk at foo.domain>
is impossible.  The list will also be reachable as <gazonk at bar.domain>
as only the localpart of the mailinglist address is used for the file
existance test.

Other than that, it is a nice hack.  Thanks :)

I believe Barry mentioned some plans for a grand bounce detection
overhaul post Mailman-1.0.

I'll try to whip something up.
