Yahoo Blocking Legit Emails

Here’s the skinny people.  If you have a Yahoo mail account, forward it somewhere else.  Get a free gmail account or what ever else is out there.  Anywhere that will actually let your get your email.  After all, that is the purpose of having an email account.  They’ve decided that since they’re Yahoo that they’ll be blocking anyone who sends them too many email bounces or what ever else they please.  What does this mean to you, you ask….

In short, anyone that Yahoo suddenly stops liking – in my case that would like be your COLLEGE – can suddenly no longer send you email.  And Yahoo doesn’t tell you that you’re not getting.  The person sending the email doesn’t get told that you’re not getting.  It just magically never arrives in your inbox because Yahoo’s mail system “eats” it. 

We’re not an open relay.  I ran the test at and we passed. 
I’ve checked all of the RBL’s and we’re not listed.  We’re an
educational institution.  We don’t spam anyone.  I’d taser anyone here
that I caught spamming through our mail server.  Now, for whatever
reason Yahoo has cooked up, we can’t send email to anyone with a email.  We get a rejection message.  The error below is
straight out of our server logs.  It’s from *my* work email address to
*my* yahoo mail address.  The subject was “test” and the body of the
email said “test to see I can get this”

27 14:50:29 mailhost postfix/qmgr[27984]: 497B11A21FE:

  1. Yahoo is also blocking hundreds of our legitimate emails.We are a small ISP with about 5000 users. Only a very small percentage of our users can send email to Yahoo, and even that is sporadic.Hundreds of our users’  legitimate emails are rejected daily with the following message:421 Message from ( temporarily deferred – 4.16.50. Please refer to email server tries resending deferred (queued) emails every 15, 30, 60, 90 and 120 minutes and Yahoo continues to defer all connections.Our email server has never been blacklisted by any other mail server or any SBL organization.I have filled out  “Yahoo! Mail Delivery Issues Form” a few times. I get the following automated response message:——————————————————————–Hello,This is an automated message regarding your recent request for Yahoo!Mail Customer Care support. We have received your message and willYarespond within the next 48 hours with an answer.Thank you for reaching out to us. We look forward to helping you!Sincerely,Yahoo! Customer Care**Please do not respond to this message as no one will receive it.————————————————————————–But I never received a  response from Yahoo and they continue rejecting our users’ legitimate emails.After reading many forums and blogs, it appears that they are doing the same thing to many other small ISPs and companies with their own email servers.This practice can interrupt many legitimate business communications and hurts many small businesses.If anyone has a resolution to this issue, I would greatly appreciate your help.
