Disagree.

- Whether greylisting itself is common or not *problems caused by encountering*
it are NOT that common.

- i.e. - WHEN greylisting IS encountered it seldom creates the postulated
richochet-until-die situation.

- Greylisting will almost certainly decline in 'percentage' use as a reasonably
good idea that just happens to not deliver quite enough gain to enough
mailadmins for the pain.

Greylisting's stats only look good until you take in the *full* picture of what
the server could/would have done w/o greylisting's aid. Usually the same job.

Ergo, I say don't fix what ain't broke in Exim if greylisting is seen as the
primary causal agent for change.

Now if *other* demonstrable gain can be had from such a change - *after*
subtracting any negatives - then lets put them onto the scales as well.
