Cannot control!

[NewOld]

I created a domain by one admin account because of DNS setting, and deleted the admin account. I thought I could not use this domain at this DirectAdmin server. The admin account was deleted, however, this domain was not deleted.

I cannot control this domain from DirectAdmin control panel. And to make matters worse, when I sent an email from this server, that email was missing. And I cannot recreate this domain because the following error message "Cannot Create Domain. Domain already exists"

I don't have a clue as to what I should do.

Correction:
I was able to recreate an account somehow.

But another question:

Even though we deleted a DNS setting domain and a host setting domain, the control panel shows 2 Domains at admin level. Is what this means that there are any email troubles at those domains?

--------edited----------------
Even though I deleted all accounts except admin account, the control panel showed some email accounts left. I am very concerned about these email accounts. What are those email accounts?

These emails account are out of control.

Message System doesn't work with those domains.
I want to clean up those domains and email system.
