This may work but your code has several problems like not handling long
lines, multiline SMTP responses and grey listing. That may cause your
code to break with some SMTP servers or give false negatives.
Instead of re-inventing the wheel, you may want to try this popular
class for validation of e-mail addresses that can check the destination
SMTP server but it handles correctly the problems I mentioned above:
