Icloud email servers rejecting emails

Recommended Posts

Recently, I started seeing emails like the welcome signup and Burt's keys emails for reviews.  But, I don't think it's rejecting order emails.  This is the error message I'm getting below and I'm wondering if anyone else has seen these?

    host mx6.mail.icloud.com [17.178.97.75]

    SMTP error from remote mail server after end of data:

    550 5.7.1 Message rejected due to local policy. Please visit https://support.apple.com/en-us/HT204137

Well, "local policy" most likely means that they think it's spam. Your description is a bit confusing -- are you saying that some mail gets through OK, and others are blocked? Can you see any pattern, such as for different return addresses or different IP addresses? If not, they might see "excessive" links in messages or other signs they think are spam. If all of a return address or IP are blocked, perhaps you need an SPF record.

Yes, I had this problem with Burts keys emails for review. It was because my host server was marking them as spam. I solved this by using PHPMailer class for added security, including a way for recipient to unsubscribe from the review emails and eliminating common spam trigger words from the emails. I found this website useful for testing purposes.

@crimble crumble Smoky did you ask your host why they were marking them as spam....it seems odd that they would be the ones doing that.  I can see the recipient server doing so but your host?

Well my host uses SpamExperts to filter incoming and outgoing emails. I guess they do this to protect their server reputation. They could never tall me specifically what was triggering it. I just removed some spam trigger words, cleaned up the html, included html and plain text versions via PHPMailer class and added an unsubscribe link. Working fine now.,

Thanks Smoky...that's interesting....here is what SpamExperts say about outgoing filtering.

I'm on a dedicated server that I control, so it's not being marked as spam from there.  I'll dig into this more and see if I can find the issue.

It only recently started and it's on Welcome emails and Burt's Key emails (requesting review), so no order emails have been rejected.  I have SPF and DKIM, Reverse DNS, etc.  This only recently started also.  My Welcome email only has email links in it and the order key only has one for the review.  But, order emails have a link to the order.  This particular server has been running for a little over a year and haven't had any other issues.  There's only a couple sites on the server without a lot of email being sent.  I was curious if others have seen this problem pop up.

John I noticed that you referenced ICloud in the threads title....aren't these the same folks giving us grief with attributes?  If so, they might have security screwed down a little tight.

PS: Do you have any Iguanas you can send me?  :biggrin:

The icloud email servers work for me.com and icloud.com adresses.  It may be some change they recently made, but I suspect there is somethng different in the email headers between the welcome email and order email.  I've modified things over time, so I'll look into that this week.

 

Do you really want Iquanas?

Now that I think about it....you're probably not the right person to ask....I hear your Iguanas fall out of the trees with the first hint of cold weather.  :biggrin:

On an episode of Bizzare Foods there were some people in the Keys that were shooting and roasting them.  I've eaten lots of aligator, crawfish, oysters, etc... , but never a lizzard.

Back to the Icloud subject.  I did some research and reading and I found some threads where various people had temporary intermittent problems with this.  I tried analyzing the email headers, but I don't see anything obvious between order emails and burt's key emails.  Maybe it's just intermittent.

I figured I'd update this thread for anyone that encounters this error.  I couldn't find anything I was doing wrong, so I emailed icloudadmin with the info on my site and server, which they list on the above link.  I got an automated response stating they would check into it and make any needed adjustments.  It also said I would not be contacted again unless they needed more info.  I'm no longer having the problem, so I guess they did something that corrected it.
