Is it possible to create a user in Red Hat 7.3 with @ symbol in it ? Example abc@abc.com is the user i need to create

Hi All,
I have a question, I want to create a user with domain name in it.
example i need to create a user name with abc@abc.com .
I get the below error when i create one.

[root@redhatunix etc]# useradd abc@abc.com
useradd: invalid user name 'abc@abc.com'
[root@redhatunix etc]#

Does any one know if this is possible ?
