Very true, but if an email doesn't bounce back at them, it's confirmed at that point anyway. ...
Not quite true...the mail system can be configured to accept any prefix to the @domain address, and not let the sender know that the mailbox is invalid. I worked at a place that did just that. I was told that it was to catch mispelling of the brokers names, but I don't know of anyone that reviewed the catch all mailbox for misspelled addresses. As a side effect spammers couldn't narrow down what was valid addresses on our domain because our mail system accepted all mail.
