Email Validation on paragraph field

In paragraph text , I want email validation

test1@gmail.com
test2@gmail.com
test3@gmail.com
test@test,com---(error)

I would like to have email validation in such a way that it should accept only email like test@gmail.com ,only gmail.com mails it should validate and if it doesn't have gmail.com at the end then throw error at the line
( @test.com in our case )
