Quote:[^]
specific Internet identifier that contains a
locally interpreted string followed by the at-sign character ("@",
ASCII value 64) followed by an Internet domain.

So everything after the @ is the domain...

Using this below Query you will be able to get domain name from the email ID

SQL

DECLARE @ID AS NVARCHAR(30)='Help@Codeproject.Com'

SELECT SUBSTRING(@ID,CHARINDEX('@',@ID)+1,LEN(@ID))

OR

SELECT RIGHT(@ID,(LEN(@ID)-CHARINDEX('@',@ID)))
