"Success delivery receipts not accepted"

Yes, I have just discovered I have the same problem - as far as I am aware, with only one correspondent. Certainly most of my emails seem to be being received ok (but how do you ever know? Even if the correspondent is getting error messages back, if he/she has only the one address for you and no phone no, they can't tell you there's a problem!).

Since the problem has been in existence for 3 weeks now with only a handful of people raising it on this forum, it must be a problem with only a tiny minority of users; so it is probably some obscure combination of settings on the sending server. The simple failure to receive any email asking for a delivery success receipt would surely cause far more emails to fail and hence a huge volume of complaints?

I have raised it with Apple Support (as an addendum to ongoing correspondence on another minor issue they have been trying and failing to address for a couple of months). I'll see what that brings. In the meantime, any more ideas on what the specific cause is would be great. My correspondent is a small business in UK (property letting agent) using MS Outlook, I assume on a small server in their office (they also have a website).

My work-around is to get them to send their emails to an alternative address in another domain I own. Although these emails are forwarded to my @mac.com address, the forwarding seems to get round the delivery receipt issue.

Does anyone know any other fix from the receiving end? I've asked my "problem" correspondent if it is possible for him to turn off delivery receipt requests. Since I am their customer rather than vv, it's not as embarrassing for me as some of you have reported, but still a pain all round.

The problem is fully described in the 4th posting. It is an Apple mistake.

Apple have implemented a non-standard "anti DSN hack" on their mail server, without first turning off DSN capability advertisments.

Or in plain speak - their server invites your server to ask for delivery receipts (The ESMTP 250-DSN capability advertisement on connect), but if you do that, their server then drops your mail.

"Apple Support" are an army of low-paid low-skilled folk who's job is to stop you wasting the time of anyone expensive. If you want this problem fixed, you're going to have to work hard to get it escalated out of the "go away" 1st-level responders area and into the second level "we will look at this problem" people.

My case is still open with Apple who have tried variations on the theme of "it's not our fault" including whitelisting a sending address (didn't work). Well beyond a joke now as far as I am concerned as it should be incredibly simple to go from a failure message to the root cause - that's the point of failure messages!

@cloughicus - have you not read this thread? The "root cause" is clearly explained in the 4th posting. This is 100% a mistake by Apple. Someone at apple with a poor understanding of SMTP has blocked mail that asks for a DSN, but they forgot to change their mail server configuration so it stops advertising that it supports the DSN capability.

What they've done is synonymous with the Ku Klux Klan putting a "Blacks Welcome" sign on their door. Apple are *literally* inviting your mail server to do something that's going to kill your email.

I have located the problem: The problem is from my MS outlook on my computer to my Internet Service Provider (ISP). My ISP claim it is a Microsoft problem. Apple and my ISP are claiming there is no problem on their side by sending a email by logging on my ISP web email site and the email is working. The problem is that all other emails is working from my MS outlook to my ISP and there are no email options to correct email from MS outlook to my iPhone or Apple. I cannot see how Microsoft has manage to block all emails to @iCloud.com and @me.com. It has to be Apple email problem, plus the error message is from Apple.

Error Message from my computer:

This is 100% a mistake caused by Apple who are violating SMTP mail protocol by offering support for receipts to connecting servers, but in fact they are blocking them.

I have the same issue with one sender. By default he requires a delivery receipt and his emails are rejected. If he turns off the delivery receipt option, his emails are delivered. It began early December.

As an independent consultant I have used Apple mail as a primary business email address since the .mac days.

I have an iMac, three MacBooks, three iPads and two iPhones, all using Apple mail services. I will be very disappointed if they do not resolve this issue.

Same with me!

I've submitted a feedback report with Apple. Several of my customers are experiencing above problem.

Thanks for identifying the problem!

.

the problem is with the automatic acknowledgment of receipt when sending emails. Send your email without acknowledgment.

I am having this issue today for the first time, sending email from my MS Outlook (using my verizon.net email address) to any icloud.com email address. However, the icloud.com addresses can send to me in Outlook.

Here's the message:

Your message cannot be delivered to the following recipients:

Recipient address: ir.....x@icloud.com

Reason: Remote SMTP server has rejected address

Diagnostic code: smtp;550 5.7.1 Success delivery receipts not accepted: ir.....x@icloud.com

Remote system: dns;mx6.mail.icloud.com (TCP|206.46.173.17|9616|17.158.8.110|25)

UPDATE: Disabling delivery receipts in Outlook allows me to send to icloud.com and that really stinks!

This means, each time I send email from Outlook to an icloud address, I have to disable Delivery Receipts in Outlook's tracking options.

Even weirder is, I am successful sending in my Outlook to icloud.com from my iPad!!!! Just not from the Windows PC.

I am using delivery receipt option.

I assume we have solved the issue; it is a Apple problem with MS outlook using delivery receipt option.

Are there some one who has Apple contacts and can use them to solve this problem as soon as possible?

Thank you in advance.
