Dave, a few years ago I had noticed something similar, but my problem was both ways. Some mails sent to my icloud account never arrived, and some mails I sent from my icloud account never got delivered.
The problem came to my attention as I was not receiving e-mail invoices from our electricity provider anymore which resulted in late payments and finally escalated into a bigger problem.
From time to time, but not often, I also heard from people that they did not receive a certain message from me or the other way around, people would e-mail me something and I'd never receive it. At the time, I always assumed it got stuck in their spam folder, but after the problems with my provider started I investigated.
I set up several mail accounts and started testing with both the messages that were never delivered to and from my friends, and also with my electricity provider. Mails simply vanished from iCloud as if they never existed. I tested and re-tested, and every time, certain messages would disappear and never get delivered when I used my iCloud account. When sending the exact same message over different accounts, they would arrive as intended.
I then stumbled onto a few blog posts describing the same behaviour, so I knew I was not alone. Allthough I don't think this is a widespread problem, I am positive that Apple has a very strict spam filter in place. A spam filter that we can not access, nor train or release messages. When I switched my mail account from iCloud to a self hosted account I iniatially received a huge amount of spam... which proves that iCloud is discarding lots of mails on the server level, before they get sent to the actual inbox.
I sent a bug report to Apple, but never got a reply.
I'm afraid, this again, is such an amazing and magical service from Apple that just works... except when it doesn't.
