Hello all, As you may know, the company ProofPoint is an Apple partner, and is engaged (I think) to reduce misuse of icloud emails.
-
We have two servers solely set up for our web-app, which is a specialised forum for apartment owners.
-
The new servers were established about the same time, with the same provider, with clean new IP addresses - and as mentioned above, are only used for this web-app.
-
During a testing phase a YEAR ago, we became aware that our in-house icloud emails weren't receiving notifications via the app, and further investigations revealed that the cause was that ProofPoint had placed a block on that server's IP.
-
We immediately, via their website form initiated a Support Ticket, which, the site indicated was lodged, BUT we have never received any response to that Ticket, nor have we received any response to four subsequent Tickets we initiated - nothing. In over a year!!
-
Yesterday, we contacted Apple support, but the devices area of support is the main section and they said it wasn't an issue they could assist with.
-
Some relevant matters:
SPF: DKIM: DMARC: are, I believe all configured correctly (and Gmail gives a PASS to all of them). The IP is not blacklisted by any list we are aware of. Our other server's IP isn't blocked by ProofPoint.
- So, literally at wits end, I'm reaching out to the developer subscribers here to see if they have any suggestions for us.
We currently are unable to accept any new subscriber that is using an icloud email address, and that's an absurd situation to be in.
Surely we don't have to go to the trouble and inconvenience of obtaining a new IP because of this!!! But when we can't get ANY response to the Support Tickets, it's really hard.
Thanks
