Issues of conversion from Linux to FreeBSD 'stat' format, etc, having been
sorted, and despite our natural aversion to greylisting, this looks good.
Very good!
What we expect this tool of yours to do is actually something subtly different
than improve rejections...
By applying it to a small subset of arrivals, we expect it to reduce the amount
of whitelisting we have had to do.
Specifics - those legit ISP's who run 'pools' of separate listed-mx and
'outbound only' servers, and the legions of singleton 'corporate' servers that
are simply not configured as they should be w/r DNS and HELO congruence, but are
otherwise 'non-threatening'.
We will be applying this to a production box over the weekend, and will see how
it performs there.
Thanks again!
Bill
