SMTP had a very useful VRFY command after you've tested for the @ and MX record, but only a handful of service providers will tell you if the email is invalid nowadays due to spam concerns.
Gmail still does though, which is a big deal as 90% of people who register on my sites are using a gmail address only and thus easy to verify instantly and notify the user to double check the email spelling.
