Apple still at there games. Yesterday a friend sent me an email to my Gmail account that forwards to my iCloud account. I never received the email on my iPhone, iPad or Mac. Only reason I know is because when I checked my Gmail account the email was there. So, I experimented. I forwarded the email from Gmail to my wife's iCloud account and to my outlook.com and Yahoo accounts as well. My wife's account did not receive it either but Outlook.com and Yahoo did. I really want to use iCloud for email but sadly is still unreliable.
