Incorrect! They rate limit everyone. If you're mail isn't being delayed,
then you do not send much mail to them. This has been an issue as long
as I can remember and nothing works to help. Use DKIM/Domain Keys, rotor
e-mail to different ips, fill out ALL there forms and comply with all
their rules. This will not put you on their whitelist and they do not
have a formal feedback loop. I have formally asked that we warn our
users to no use yahoo email addresses for this reason. As a matter of
fact, I have been able to work with every other large e-mail provider/
ISP (AOL/Comcast/Netzero , etc...) and work out e-mail issues with them.
I even have several contact numbers directly the administrators of these
companies. Yahoo simply sucks in this regard and they have not yet
figured out a way to properly set up restrictions so bulk e-mailers may
send e-mail. If you are going to store the largest numbered e-mail
accounts, then you will receive bulk mail.
