What you want to do is theoretically possible, but it will not work reliably. Accoprding to your specs you would need to use Net::DNS to find the primary MX and then use Net::SMTP to talk to that box. The SMTP command you're looking for would be "VFRY" - however, you should be aware that nowadays many mail relays either respond OK to any VRFY query, or don't implement the command at all for security reasons. And that does not even count the cases when a mail relay can't know the user names becauise even though it is primary MX, it is not the box that holds the user accounts.
