qmedic -> Reason: Illegal host/domain name found (19.Nov.2014 5:36:05 AM)

Some Verizon email users are getting the following message when emailing my company:

Your message cannot be delivered to the following recipients:

Recipient address: name@amhsi.org
Reason: Illegal host/domain name found

Its only verizon, att and comcast that we can see - all other email providers send through. Nothing on the server has changed and Verizon says we are not blacklisted.

Any advice??

Thanks
