Never mind that last, I didn't see "CataList".  But the URL referenced
in CataList is actually correct.  The problem is once you make the
connection, it tries to look up "lsv1.listserv".  This is likely caused
by some error in the configuration, but I'm not sure exactly where it
would be, considering that the interface works correctly when you go
straight to it and that the URL reported by CataList is correct.
