regex

I tried the reg expression

^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z])+([a-zA-Z])+

for the email validation.

Since I want the user to allow submitting even with the empty email address. So I changed the reg ex to

(^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z])+([a-zA-Z])+)?

But this expression accepts any email address without any validation.
