smtp is an unreliable mail delivery protocol. It has a "failed
delivery" option, but hardly anybody uses it for security against
spam.
So, even if you do parse the logs for failure messages, it is unlikely
to be 100% reliable.

There are other options for checking email address accuracy.
User enters email address in web site.
web site sends a special email to that email address.
Until the user respond/reply to the special email, the email is
assumed to be invalid.
Much like the method most email mailing lists use.
