This too was discussed in the Imail forum. Someone actually did some testing with the domain keys. The greylisting is not totally valid as emails were passed with and without the keys. It seems to be a random issue in the sense that there doesn't seem to be any particular pattern to the failed emails.

I had heard that Yahoo.com was using greylisting on all email that did not support domain keys. Don't now if it is true, perhaps a rumor may be worth checking out.

Please forgive the off-topic message. I'm receiving a bunch of deliver failures today for Yahoo. The message is: Failed Recipient: [EMAIL PROTECTED] Reason: Remote host said: 451 Message temporarily deferred - [190] I searched google and I searched Yahoo's site to see if I could find an explanation of this message -- no joy. I didn't know if it meant they are blocking our IP or if Yahoo was having problems. It sounded to me like they are blocking us. I could not find anything on Yahoo's site about who to contact, what the message means -- nothing. Can someone shed some light on what may be going on?
