That last word makes it appear you are confusing efficacy

Efficacy has nothing to do with the success/failure of DNSBLs in a
general sense.  Nor is rejecting at source a necessary consequence of
DNSBLs.  We use DNSBLs, do rejections, but still get to quarantine the
whole email.

What I intended to say is that the DNSBL's efficiency (if that) isn't
relevant to success/failure _unless_ it impairs its useability.  And as
such, that's a per-instance issue, not generic to the technique.
