Undelivered Mail Returned to Sender--Why do I get about 10-15 of these per day?
Over the past year I have begun receiving 10 to 15 emails per day from Apple with the subject title, "Undelivered Mail Returned to Sender", but I don't understand why.
There is a lot of verbiage in the body of the email, but it is technical to the point that I don't understand it.
Is anyone familiar with this issue?
iMac 21.5″, macOS 10.15
