550 550 relaying denied (state 14)?

Please help. I see there have been a few similar queries over the last few days, but none answered that I can see.

I have had this account for 5 years, other than that's it's slow, I rarely have problems.

Since last Tuesday about a 3rd of my incoming mails are being rejected. Those trying to mail me, get the following:

Technical details of permanent failure:

    I did a little deeper investigation on this issue and here is what I came up with:

    It is clear that Yahoo europe has a problem with one of their email servers.

    Let's first find out what the servers are for Europe:

    (I use yahoo.dk in this test)

    host -t mx yahoo.dk

    yahoo.dk mail is handled by 10 mx1.mail.eu.yahoo.com.

    yahoo.dk mail is handled by 10 mx2.mail.eu.yahoo.com.

    This shows us that there are two servers and they both have the same preference level (10).

    Okay, let us see if there is an error with server 1:

    telnet mx1.mail.eu.yahoo.com 25


    Connected to mx1.mail.eu.yahoo.com.

    Escape character is '^]'.

    220 mta145.mail.ukl.yahoo.com ESMTP YSmtp service ready

    HELO mail.test.dk

    250 mta145.mail.ukl.yahoo.com

    MAIL from:<jesper@test.dk>

    250 sender <jesper@test.dk> ok

    RCPT TO:<autisten@yahoo.dk>

    550 relaying denied for autisten@yahoo.dk

    Relaying denied, so clearly there is an issue with this server.

    Let's check server 2:

    telnet mx2.mail.eu.yahoo.com 25


    Connected to mx2.mail.eu.yahoo.com.

    Escape character is '^]'.

    220 mta128.mail.ird.yahoo.com ESMTP YSmtp service ready

    HELO mail.test.dk

    250 mta128.mail.ird.yahoo.com

    MAIL FROM:<jesper@test.dk>

    250 sender <jesper@test.dk> ok

    RCPT TO:<autisten@yahoo.dk>

    250 recipient <autisten@yahoo.dk>

    Aha! Server 2 will accept our emails for yahoo.dk.

    This explains why the error is random. When mail is delivered to server 1, it fails. But if it goes through server 2 it will get delivered.

    Only quesion that remains: Who will fix it?

    550 Relaying Denied

    Same problem here ("550 relaying denied for..."). Seems like there is something wrong with the yahoo.se mail server since around last week. Sometimes incoming messages are received, sometimes they disappear. Yesterday I sent 4-5 consecutive test emails from the same address to my yahoo email and some of them went through some not. I tried again today with a similar test, but this time all of them disappeared! That's quite bad since people can be missing emails like verifications to applications, shopping orders, etc. I hope yahoo is aware of the problem and is working on it...

    Ditto here (yahoo.ie address).

    Problem for about 8-10 days now, contacted support about a week ago, no response.

    You'd think they'd post something, somewhere acknowledging the issue. I've lost shopping order e-mails, ebay mails, mails from work, mails from friends.

    People should jump ship to Gmail if this goes on any longer. Poor show by Yahoo.

    Same here - e-mails seems to disappear randomly. I have tried to send e-mails to myself to test this - some are received, others are returned with an error message like the one above, and the rest disappear with no error notice at all.

    I hope this will be solved soon - I have also sent an e-mail to Yahoo!, but no reply so far...

    The same problem here. My email was down yesterday and then worked temporarily during the night between Sunday and Monday before it went down again. Wrote Yahoo yesterday but no replies what so ever and it is still impossible to send emails to my Yahoo address.

    I'm having the same problem - my address is a @yahoo.dk. I have written to them 3 times now since Friday and despite the "you will hear

    back from us within the next 24 hours with an answer" I still haven't heard from them. Getting quite frustrated since I'm using my email for work as well...

    I have exactly the sam probelm with yahoo.dk mail. Seems like there are quite a few of us now with same problem. SO hope that someone at Yahoo will pick this up and fix it! We are all losing important mail so they need to restore all the messages that have been sent.

    I have the same problem. Some mail bounces (error 550). No help from Yahoo (4 days since i wrote to them). This is annoying!

    I called Yahoo Technology Norway today, they are however not the one dealing with emails, but they said they became aware of the problem today and had brought it further to Yahoo mail in U.S which was currently working on the problem... so if they are as smart as the one above they might correct server 1 soon :)
