This shows that email should die in a tyre fire and we all need to collectively move to something else… but we should have done this more than 10 years ago.

Email has SO many technical issues that if someone would have come out with email today, nobody would use it!

The ONLY thing going for it really is that it’s decentralised and has the network effect that almost everyone uses it. Bzzzt, I kid I kid!

Anyone under 25 will tell you they do NOT use emails and instead prefer instant message, and is email really decentralised? NO!! Try setting up your own relay and you’ll be dropped by any big service. Gmail+Outlook is basically a cartel with zero recourse!

Hmmm… could there even be a case of anti-trust given Gmail’s behaviour

iCloud Custom Domains & Mail are filled with bugs. My favourite one is that if my custom email I want to register has EVER been associated with an Apple account, it can never be used as a custom domain, unless that domain is set to catch all; it is impossible to add that specific address; it just errors without any specific message. The original account was fully deleted; going to the arduous process they set up that takes weeks to actually delete the account.

Customer support is worthless for actual technical problems as usual for Apple. Fun extra regarding customer support; if you arrange a support call in a language not native to your region, they honor that, but that information is lost if they escalate the call; the callback is always in the national language, despite explicit requests over the phone during the callback schedule

So, Apple sends the wrong EHLO domain when trying to send emails out. This results in them dropping emails to their own users. Can't get past Apple's level 1 support. How can I get to someone that maintains their SMTP k8s cluster?

Ah yes. If you are having problems with your email, send us an email.

Yep, whenever I start a new job I say "Don't worry, because iamverysmart, you don't need any Microsoft products!" I am then hailed as a genius, everyone claps, and I get a big fat raise.

I’m reading this in bed and nearly woke my wife when I read “my ass clapped” LMAO!

This was mentioned earlier today on the mailop list: https://www.mail-archive.com/mailop@mailop.org/msg24300.html with a later response indicating that Apple was aware: https://www.mail-archive.com/mailop@mailop.org/msg24312.html

OK, that response is from an actual Apple employee, so does look promising.

The biggest problem with huge corporations is that sometimes it's next to impossible to actually communicate with them. Does anyone have any good contacts at Apple?

I sent this more than two weeks ago:

  Subject: Issue with Apple's SMTP delivery
  
  Hello,
  
  I've had several issues reported about email delivery from Apple. The error they have in common is this:
  
  Mar 12 21:38:17 daisy sm-mta[28249]: 52CLcCoi028249: ruleset=check_mail, arg1=, relay=p-west1-cluster6-host7-snip6-8.eps.apple.com [IPv6:2a01:b747:3003:204:0:0:0:47], reject=550 4.1.8 ... Access denied. HELO does not resolve. (HELO p00-icloudmta-asmtp-us-west-1a-1.p00-icloudmta-asmtp-vip.icloud-mail-carry.svc.kube.us-west-1a.k8s.cloud.apple.com)

  Looking in to this, the resolution of "p00-icloudmta-asmtp-us-west-1a-1.p00-icloudmta-asmtp-vip.icloud-mail-carry.svc.kube.us-west-1a.k8s.cloud.apple.com" results in this list of MX:

  mx-in.g.apple.com
  mx-in-mdn.apple.com
  mx-in-hfd.apple.com
  mx-in-ma.apple.com
  mx-in-rn.apple.com
  mx-in-vib.apple.com
  mx-in-rno.apple.com
  mx-in-sg.apple.com
  
  All but two of these resolve to A records.
  
  Two of those, though, resolve to more MX:
  
  host mx-in-rno.apple.com
  mx-in-rno.apple.com mail is handled by 10 mx-in.g.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-vib.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-rno.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-rn.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-hfd.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-sg.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-mdn.apple.com.
  mx-in-rno.apple.com mail is handled by 20 mx-in-ma.apple.com.
  
  host mx-in-mdn.apple.com
  mx-in-mdn.apple.com mail is handled by 20 mx-in-mdn.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-sg.apple.com.
  mx-in-mdn.apple.com mail is handled by 10 mx-in.g.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-vib.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-rn.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-hfd.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-ma.apple.com.
  mx-in-mdn.apple.com mail is handled by 20 mx-in-rno.apple.com.
  
  This loop is a mistake and should be fixed.
  
  Additionally, RFC 5321 section 2.3.5 says that the name given in an EHLO / HELO greeting should be an IP literal or a primary host name ("a domain name that resolves to an address RR"). The name given in the EHLO / HELO exchange does not resolve to an address RR; it only resolves to an MX. While this is technically incorrect, the looping MX is the real issue. However, if you're fixing the looping issue, you may want to consider fixing this issue at the same time.
  
  Please look in to this, and please let me know if you have any questions or need any additional information.
  
  Thank you,
  John Klos

They also started using new IPs without PTR records to send out mail. Though so has Microsoft just recently. Both heavily frown upon that when receiving mail themselves. Do as we say...

I hate getting a report telling me my work domain is blocked because it is missing a PTR record and we use Exchange Online. I can’t do anything about that!

sure you can, take your business elsewhere

Ah yes. If you are having problems with your email, send us an email.

It’s not very hard to register an alternative email account somewhere.
