Sorry for the Off Topic thread but I’m at a loss
Is anyone else having issues sending mail to Yahoo?
They are returning 421 Message temporarily deferred to every message
my servers try to send. My server then retries like it should but
yahoo never accepts the message, even after day of retrying. Google
turned up several people having the same issue but no one with a
solution. My DSN is right, I have SPF records, and sign outgoing
messages using DomainKeys.
I’ve filled out every form on the yahoo support site without any luck
at all. Anyone else seeing this problem or know of a way to get to a
real person at yahoo? There are a few reports online that yahoo has a
paid support phone number that will fix the problem but no one list a
phone number, and as much as I don’t want to pay yahoo just to accept
my messages I’m running out of options and the customer complaints are
getting more frequent every day.
Almost everyone. Tell your customers not to use yahoo ids :-(
I dont know if there is any standard reason , But I think yahoo defers
mails from an IP when there are 'n' message attempts to incorrect ids. n
being too low for any practical server.
Also keep your rates of delivery low .. lest you enrage the yahoo guys.
( Their server , their rules :-( )
On my servers I ratelimit yahoo deliveries and deliver thru a separate
server. Also keep changing the smtp bind address. That helps a bit but
yet mailq is always quiet high. We have already told our servers yahoo
defers our mails so it is not in our control to get done
BTW if you get any solution please share with me too :-)
Thanks
