This has been a feature of recent spam, which is probably why it's now
an issue. Several spam senders are now having sender addresses of
<spammer>@<spamdomain>, where <spamdomain> resolves via DNS to
'0.0.0.0'.
Eventually qmail rejects the message because it recognises that it's
looped around too much, of course.
