unknown "customer user"

[gawkla]

Hi Everybody.
I found this question asked in the past, but without any answer.

How to easy find & manage users which were created automatically after receiving email ticket from unknown email address / unknown customer.

If this email is not present in system new customer user is created. How to easy filter out these users and how to easy manage / join these account to real customers / companies?

I know bad customers for me have @ in the customer ID.

Yes, this is true. Because CustomerID = email address in this case.

But how is the easiest method to manage these accounts? How to list only these tickets?

I know that I can list all tickets and manually find tickets from customers not belong to known company [with @].
Next I can manually edit all these tickets and set proper CustomerID inside ticket. I can also connect to database directly and try to edit affected records directly in database.

Any other idea? What is recommended path?

--- in other words:

Generic Agent works nicely.
