Hi,

When I try add new domain test.pl (it's a fake domain but in fact ends at .pl), then I have some error likes:

Wprowadzony adres e-mail należy do innego wdrożenia/regionu. Aby uzyskać pomoc, skontaktuj się z support@zohoaccounts.com.

In English this means: 

The e-mail address you entered belongs to a different deployment / region. For help, contact support@zohoaccounts.com.

So, what I have done wrong?
