Emails bouncing back to senders

[Matjan]

Need some help! I was contacted yesterday to say that emails being sent to my yahoo sky account are bouncing back when the day before I was getting them ok. Any ideas on how I fix this ? Still getting emails into the account so it's still working.

What's the failure reason given with the bounce message? It's hard to be able to help wothiut knowing why the emails have bounced.

 this is the response that my sender received

It is difficult to say what is happening but I doubt your emails are bouncing, if that is legit then it could be the issue is at the other end and not anything amiss with your account as that image doesn't really appear as a bounced email as it would give more information like the reason for the bounce, whereby that says nothing.

I agree. The message just says it was generated by the sender's email server. But it doesn't actually contain any diagnostic information at all or any failure reason.

Error 554 is often associated with spam/junk content within the email being detected. It's not to do with the addressee (you).

As @Mark39 has said this appears to a problem with the settings on the person's account you are trying to send these emails to.

Hello, would you help please? A contact is trying to send me emails but say they are getting bounce back messages (but i am receiving emails from others) . They got the following 2 error messages when sending to my outlook email:

 Error message 1:

There was an error while attempting to deliver your message with [Subject: ]
to      MTA p3plwbeout15-03.prod.phx3.secureserver.net received this response from the destination host IP -  Unfortunately, messages from [173.201.193.38] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [DB3EUR04FT026.eop-eur04.prod.protection.outlook.com]

Error message 2:

This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed permanently:
*  (outlook email here) 
Reason: There was an error while attempting to deliver your message with [Subject: "RE: hearing follow up"] to (outlook email here) . It has been in queue too long, and will not attempt delivery again.

Is this a problem at my end or theirs and if so why?

Thanks! 🙂

@luckyz I'm not an expert but they look like sender failures, rather than associated with you, the recipient.

The part of the first failure message that reads "...part of their network is on our block list (S3150)" is likely to relate to both failures, which I take to mean that some part of the routing involved in sending the message is blocked, probably because it has been associated with junk or spam mail.

@Mark39  thanks does that mean their system i smarking my email as junk?

[luckyz]

@Mark39 if it was at my end my system would have told or forewarned me of any issues that were causing bounceback or that my email was 'permanently, not available. but i did not get any .

I don't think so. The failure message talks about some part of the sender's network, not you, the recipient.
