I've made a new organization-wide e-mail address. The e-mail address is a Google Group (e.g. customersupport@businessname.com).
Unfortunately I am not able to receive the email with the verification link.

Things I've tried (without success):
- Create another organization-wide e-mail address with a new Google Group
- Create another organization-wide e-mail address with an existing e-mail address (e.g. employee@businessname.com)
- Add the Salesforce IP Addresses to the whitelist of our organization in Gmail (https://help.salesforce.com/apex/HTViewSolution?id=000003652&language=en_EN)
- Write an inbound e-mail service that creates a task when with the body of the email (http://salesforce.stackexchange.com/questions/4188/gmail-forwarding-address-verification-code-for-apex-email-service). Couldn't get this to work. I'm quite new to Salesforce Development.

Does anyone know how to verify the e-mail address? 

Recently we made a copy from our production environment to our sandbox environment. In the production environment we made a site that works fine. In the sandbox, I made a change the 'Active Site Home Page' visualforce page from the site. When I click the [Preview] link next to the Active Site Home Page the changes are visible. But when I view the site via the domainname the changes aren't visible. 
I also tried to make an new webpage but that won't work either. All I see is a "under construction" page.  It feels like the link goes to the wrong environment.

Could this have something to do with the fact that we changed our company name after we made the production copy to the sandbox?

I'm quite new to salesforce development, could someone help me?

I can not seem to figure out how to get a profile to show up here. There doesn't seem to be a default profile under my profiles called external identity. How do I get a profile to appear here that way I can allow self-register
