Cannot receive mail from Holiday Inn
I am not receiving confirmation e-mails from Holiday Inn. Even if I forward their e-mail from a different e-mail address, I am not receiving them at all within iCloud. It drove me crazy this morning and I have done MANY tests. I finally had them send it to my work Google account and received that right away. I have forwarded it to/from different accounts and finally narrowed it down to iCloud is blocking the e-mail. It is not in junk and I have tried aliases and any confirmation e-mail from Holiday Inn that I try directly or forwarding from several other accounts is not getting through to my iCloud account.
What in the world? This is making me wonder what other e-mails may be blocked by iCloud, because I KNOW that these are being blocked and not getting through. Any idea where/how to check into this further?
