I need a Java application that for a given email address can verify that the mailbox actually exists without sending an email to the user. I think the trick is either in JavaMail, or in using telnet. Note that you there are packages which verify the format of an email address, or can tell you that the smtp server for that address exist; this is part of what I'm looking for, but the main part that I'm looking for is to verify that the mailbox actually exists (Without sending an email).
Acceptance test would be that I feed 100 email addresses from different domains, and see the result. Some of these email addresses actually exist, and some don't, and the program should be able to correctly tell me if that mailbox exists or not. You don't need to set up any kind of sophisticated input method; command line would do fine; I can just feed your program one email address after another on command line.
