This has to balanced against the reception of spam. Filtering out a thousend
of spam messages and loosing a few mails from domains run by cluless
admins might be worth it.
There is clearly a limit of "how bad" a site can be run and still
be recognized as a peer whom we want to communicate.
The point is to notify the cluless admins that "their domain stinks" and
give them a chance to fix it. Those who don't care - well i personally
could manage without them.
