Reject all email to my iCloud email address from a specific email address.
I want to reject all email to my iCloud email address, from a specific email address. I don't want to send the mail to junk, I want to reject it. Does anyone know how to do it?
I found some old posts that refer to Blocking, but the Block command does not seem to exist in the current iCloud 2018.
