When can we reach iCloud?

[#1]

Emails to iCloud are still being rejected "due to local policy". This typically happens when Apple's internal filters decide the messages or sending practices do not meet their standards. I know this has been a problem even before Plusnet transferred the email service to Greenby. But when will it be solved?

The last time I had a failure to friend@icloud.com and friend@mac.com I re-sent the email as plain text and it wasn't bounced - could be coincidence of course.

iCloud delivery rejections repeatedly looks like :

Useful info. The iCloud rejections started about 2 months ago without any changes in my classic Outlook 2019 program.

Any chance of Plusnet fixing this problem before outgoing mail for migrated plus.com accounts is switched from relay.plus.net to the Greenby proxy?
