Hey, let's not be *too* judgmental here. I'd say this is *risky*, but
not necessarily "insane". Maybe it's "insane" if the mailing list in
question is advertised and well-known to the entire Internet, but we
disabled the "lists" command in majordomo except for a couple of
lists that are intended for the general public (and those lists
*are* moderated) and disabled the expn command in sendmail.
The reason we do this is that we have lots of users at sites that
are very minimally on the air. The users do not necessarily know
that if they subscribe from one workstation and post from another,
the addresses don't match. We also don't want to moderate those lists,
so we leave them open, conceal their existence as best we can outside
the user community they are intended to serve, and acknowledge the risk
we are taking. If and when a list of this type does get hit by spammers,
we'll have to moderate it, but I assure you we are not insane :-)
