Hello Autoresponse not sending to our domain emails

Hello I have almost completed my form and noticed auto responses don't send to our domain email address (johnh@theholcrofts.com or johnh@tortoisestorage.com). They are sending fine to my hotmail account. I am concerned that it won't work for anyone else with a company domain email address. 

I am receiving all form fill notifications perfectly to my domain email address, it's just the auto response that doesn't work. 

Look forward to hearing from you. 

Thanks

I have checked your latest edited form and can confirm that Autoresponder emails were sent properly for the addresses you've entered. If you have not received any, please contact your corporate email service provider and request them to add JotForm's IP addresses to their whitelist.  Here are IPs:

You can also check the spam folder to make sure that the email is not there. If it is, please mark it "not spam". 

If the issue persists afterwards, please let us know, so we could investigate further.
