I was looking for a good list of ip ranges to whitelist and came across one maintained at PureMagic.
Here's the current version: http://cvs.puremagic.com/viewcvs/greylisting/schema/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 # retry several times within seconds, and then bounce the mail, 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?
