Cannot receive email from ratbrew.com

Cannot receive email from ratbrew.com

I have a forwarder set up so that all email sent to my @ratbrew.com email address forwards to my zoho account ( joel@dwbrewing.com) I am not receiving any of these emails even though the server at ratbrew.com has verified the outgoing emails. I have attempted several emails all within the past hour and none of them have come through to my ZOHO account, nor do they bounce back to the outgoing server. I cannot see any settings in my account that would be causing this and I have added ratbrew.com as whitelist. Please help :)
