The way to do this, according to the SMTP specification, is to send a VRFY request. This came up on the list yesterday, if I recall correctly. However, many mail servers either disregard VRFY or send back a status code that doesn't indicate whether the email address exists. So, the only way you can really confirm the existence of an email address is to send a message to it, and receive a response. MX records have nothing to do with this, by the way. You use MX records to find the mail server in the first place.
