I have purchased "@secretsleepers.us" and am trying to link email to it, but keep getting this error message. Then, when I try to add an email address, it keeps marking it as spam. I'm trying to register a business with Zoho and plan on putting considerable money into this, but if this keeps up, I'm most certainly not having any business with Zoho as Zoho seems hellbent on running me off. Any help would be appreciated.
