Perhaps odder yet - my SA applied the highest score, yet is has Bayes OFF and if
it has started doing any form of RBL, I've got to have a go at it and see what
the upgrades have dragged in under the radar.

Did see a mention of filtering for PowerMTA in the SA list, but haven't seen any
code yet. DATA is 'too late' to block on that - I don't want the message on board.

.. and 'travel industry'?

If there is anything left of it after TSA and volcanic ash disruptions, they can
use a more polite MTA - else pack it in, retrain as parasites and run for
public office.
