new users command line

I recently updated to a dedicated server, in the process I updated virtualmin to the latest version. When I run my scripts to create a user, I'm getting a different result than I did before I made the switch.

Here's the command line call:

virtualmin create-user --domain example.com --user fred --pass password

on the old setup this would create fred@example.com and fred-example.com and assign them to the same user number.

on the new setup, this creates fred.example.com...hmm where is the setting to change that back to what I had before?

Thanks
