It will be interesting to see how this works in practice against one
pathological bouncer I have on the exim list...
Approximately one message in 10 (by volume - I can't match the bounces
to any particular message) generates a bounce which has no useful
information in it at all.  The exim.org box is still running Mailman
2.0.x (very old box - about to be replaced with something with a better
than clockwork CPU) so I can't do generic VERP , but VERP probes have
failed to establish the link to the original address on the list... I am
now wondering if someone is just sending me random bounces for the hell
of it....
