This is a must read if you have Yahoo mail ids or if you send mails to Yahoo ids.

Do you have friends with yahoo ids? Is your company using Yahoo ids to receive messages? Are you sending mails to yahoo ids? If you answer ‘Yes’ to a single question then don’t miss the information below.

Of late Yahoo! Mail has become more aggressive in its acceptance of SMTP connections and denies connections with error message “421 Message temporarily deferred.”

In simple language yahoo bounces mails for reasons well understood by yahoo. Don’t be surprised if you mail bounces from a 5 year old friend. No, I am not kidding. Those of you who have visited iPOTT will know we have a simple registration process to help ‘buyers’ search software. We have many registered users who have used yahoo ID to register. We also have a lot of users who have subscribed to newsletters and software information with yahoo ids. We have been sending information to our users for last one year, but this month out of the blue; all mails to Yahoo ids were returned. The message yahoo is sending back is of course positive ” your mail has been temporarily deferred”, “No action is required on your part”, “we swear to deliver your mail” “I am sorry to have done this”, (ok, ok, you can leave out the last two quotes they were mine).

Of course we are troubled that we are not able to send our yahoo users’ mails. By the way how does the user “YOU” know you have missed our mail? Ask yahoo! So I think yahoo users are more at loss not receiving what is meant for them. We have contacted yahoo (using the above help link) informing them about our mails and our users. I will surely post on this blog when I receive the reply. Depending on this response and response time, we will have to take a call to disallow yahoo ids to be used during registration process.

If you ask me can this be resolved - TRY! Also try reading http://www.ahfx.net/weblog.php?article=107. I wonder what or who made them strike out certain sentences form the article Watch this space again!
