Andy,
Phenominal find! I've been seeing the same issues on my server and
figured it was just remotely "misconfigured" servers, but this
explains it much better. Hopefully we can figure this out.

I was looking for a good list of ip ranges to whitelist and came
across one maintained at PureMagic.
Here's the current version:

whitelist_ip.txt?rev=1.16&view=markup
While going over it, I read this:
# Because error code 450 is most commonly used for a mailbox lock
failure,
# many sites seem to treat it as a very short duration failure, and
will

while they
# handle a code 451 more "normally".
When I checked my mail logs, sure enough, I saw various SMTP servers
try to immediately re-send a bunch of times all within 1 second of the
first 450 reject for being greylisted! These servers looked
legitimate.
So I looked for a way to try changing the reject code from 450 to 451
but couldn't find it.
Ideas? Comments?
