Apple blocking legit inbound email

tried to talk to apple about this as im on the same boat...

and i got someone whos asking me which mac i'm using...

and after 5 mins of trying to explain, i'm on hold forever

and there's no mail address where i can forward the error message...

Apple are not blocking it, ProofPoint are, contact them.

Who is ProofPoint and why are they blocking email to icloud addresses? The link you provided does not link to a contact page; it only told me that my ip was not being blocked by them!

Ask them, they are doing it.

You are most helpful (NOT!). Luckily, there are other discussions where participants have dug a bit deeper.

Apple has to have an agreement with ProofPoint, otherwise Proofpoint would not be filtering email to Apple icloud users. Several IT managers commented that ProofPoint was erroneously blocking their IPs and refusing to respond to their requests to change. So, yes, Proofpoint would be the one to ask, but since they aren't responding, it is time for someone from Apple to wake up and either subscribe to a different filtering service, or push ProofPoint to improve their resolution of false blocking.

Then tell Apple instead of other Apple users.

You have just been helpful by providing a link to support your comment.

I am not a professional user. I came to this page through what I thought was a reasonable process of trying to find information on Apple's website. It has taken me a while to appreciate that clicking on a link in Apple's Support area would take me to a discussion where people like you would just snarkily point out how stupid they think you are rather than offering THEIR SOLUTION to the problem.

By telling other Apple users about my problem, I would hope that others with the same problem would either tell me what they did to resolve the problem, would have the dim comfort of knowing that they weren't the only ones with that problem, or would be fired up to also "tell Apple".

If I were Apple, I would certainly monitor discussions that I was hosting on my corporate website so that I could see what people were saying about my product. There are plenty of forums for discussion just like this where there are company representatives who will pipe in when appropriate to help out.

I'm on the phone with apple support right now about this. I'm being escalated to a senior technician. They recognized the error:

550 5.7.0 Blocked

It's not my IP, so it much be either my specific address, or possibly the entire domain.

Indeed, ProofPoint is the company doing the blocking, but they are doing it for Apple. So Apple is the path to take to get this fixed.

It will be interesting to see what Apple has to say.

Seems to be an intermittent issue at ProofPoint - they are looking into it.

Apple only monitors critical posts about their company not about problems users face.

they censor comments on bad upgrades, strategies to force people to upgrade, but never solve anything when you have a problem
