Apparently your web server isn't defining the HTTP_HOST environment
variable when running CGI scripts.  The CGI/1.1 spec says that
SERVER_NAME should hold

  The server's hostname, DNS alias, or IP address as it would appear
  in self-referencing URLs"

(but doesn't mention HTTP_HOST...), so with the below
(just-checked-in) patch Mailman falls back on SERVER_NAME when
HTTP_HOST is unset:
