I think you're confusing greylisting with confirm-delivery.
Greylisting happens in the mail system, and sends unrecognised SMTP
contacts away with a retry later (450 response?) the first time and any
time in the next short interval (eg 5 minutes). A real mail system will
come back later na dbe let in. Your cheapo SMTP spew-the-net will simply
fail and not return.
Personally I publish my real address. I use spam filters but also autofile
all "personal" email not from a known address in my UNKNOWN folder,
which I peruse about once a day. Genuine messages get their addrs added
to "known".
