And yet Googles server farm has no problem with greylist-milter. I mentioned that this was with greylist-milter, you are merely shifting your claim now to essentially blaming greylist-milter for not issuing a standard SMTP error 4xx. Yahoo is not the only mailserver that misbehaves with 4xx errors. As a result I have always vastly overbuilt my mailservers so that there is never a chance of them issuing a "real" 4xx error because they are actually too busy to accept mail. I certainly cannot trust any mailserver or mailserver farm on the Internet to handle a "real" 4xx error correctly, thanks to miscreants like Yahoo who apparently think it's OK to mishandle some 4xx errors and not others, and who have provided cover for the other boneheads to do the same thing.
