HTML pattern for email to a specific domain

Question

I'm trying to find a regex pattern that only accepts email with a specific domain as follows.

z= [a-zA-Z0-9]

y= [a-zA-z]

(1) [email protected] (eg: [email protected], [email protected])

(2) [email protected] (eg: [email protected], [email protected])

Currently what I have so far is: [.a-zA-z0-9]*@domain.[a-zA-z0-9]

Could anyone help me on this?
