For those who use Apple (@icloud, @me, @mac.com) accounts: my apologies for the almost comical delays (days) in delivery times for these emails. I’ve determined my email provider is not that interested in fixing this issue, so I’ll be changing providers in the next few weeks. I hope it will not disrupt service and deliveries to Apple domain servers become as timely as deliveries to all the other major email services.
