We have most of our servers set to silent dump any invalid email addresses. It's too much of a resource hog to send all those bounces, not to mention some blacklists will now blacklist you for bouncing.
It's a dirty tactic but you could always use html mail with a hidden image to track opened messages.

According to my own experience, this is not possible, due to the fact that most mail servers do not strictly follow standards when replying to SMTP request. Some will reply that the user address is unknown, but some will will not, simply accept the message and bye ! -- _______________________________________ REUSE CODE!
