I have two servers:
Server1 is a simple Master Server where into DNS I have created domains and subdomains.
Server2 is the real application server where I will have the users applications and webmail.
If I try to create a Virtual Server in Server2, for example always my-domain.tld (to be able to then install in this an application) , an error is returned to me because the domain already exists.
On the other hand, if I try to create a Virtual Server in Server2 corresponding to a subdomain, for example crm.my-domain.tld, Virtualmin creates it without problems although this is already existing because it is present in the DNS.
I have no idea how to resolve the situation.
Thanks in advance for any advice.
