The recipie is fine, it is just that only `newer' mailing lists are likely
to have implemented RFC2369. Slug, unfortunately, isn't one of them.

        another would be [EMAIL PROTECTED], I think

I've found, emperically, that only spammers are using the spectrum submission
addresses so I blackhole mail sent to those.

The problem is that since Slugs' mailing list doesn't implement some form
of List-Id or X-Mailing-List identifier you need to pick something constant
to sort on.

Using regular expressions beings that down to 1 sender and 2 different `To:'
addresses. Filtering on sender is bad because if a mailing list moves
your filters break. Filtering on To: is bad because when you start to have
people sending Bcc to a lists (or list to list discussions). Having a 
constant identifier helps.
