Need email reset

I created an account with a primary email id of admin@phualvatimes.com but I needed all email send to admin@phualvatimes.com forwarded to a group admins@phualvatimes.com - which had a group of email addresses mostly external gmail. I set it up the forwardng but it never worked. So I deleted admin@phualvatimes.com and made my gmail email as the primary. Now when I try to create admin@phualvatimes.com as an alias of admins@phualvatimes.com, it tells me the email already exists. So please clear admin@phualvatimes.com from the database and make it available so I can make it a group name/alias.

Thanks
