What is the primary site URL configured in admin mode as described here: http://webhelp.episerver.com/latest/cms-admin/managing-websites.htm ? 

Thank you so much for your quick reply. I really appreciate it.

The primary and only website URL configured there is "http://fakecompanyname.com/".

When I click on the name of the website I see the settings for the configured website and in the section "Host names" there is a table that looks like this:

The URL "fakecompanyname_ep20.episerverhosting.com" seen above is the same URL that is displayed when visiting links in the confimation email sent to the user after a form submission.

Thank you for your time.

Would it be possible to try removing fakecompanyname_ep20.episerverhosting.com from the hosts list and see what effect it has?

I am not sure if I am allowed to do that because it is for the production environment but I will investigate it. Do you perhaps know if there can be any consequences by removing it from the hosts list?

Also do you think the order of the URLs in the hosts list has any effect? 

Thank you again for your time and knowledge.

If you cannot do this in production perhaps try in a non-production environment?

In terms of asking about removing the domain name in production it would be worth raising a support ticket to get the question answered: https://world.episerver.com/support

I probably will try to recreate it in a non production environment and as you suggested I have now raised a support ticket.

Thank you for your time and help. Have a nice weekend!
