Server-side global content-based filtering is silly, unless of course
it's your (private) server. Users are expected to do their own
filtering, otherwise they're exposed anyway. Server-side filtering (on
public servers) is just false sense of security.
Moreover, this is not a US-only list. In some countries unattended
filtering of messages addressed to third parties might be illegal per
se, virus, spam or whatever included (at most, you can add a header to
the message if you think it's spam or virus, but you _have_ to deliver
Mailing lists may be special cases (think of moderators), but still you
should never rely on the server, you should implement a strong client-
side filter anyway. And once you have a strong local filter, additional
security provided by a remote (weaker) one is negligible.
