I'm totally confused by your authenticated as valid part, lmtp doesn't
authenticate anything.
How do you let postfix know about valid recipients, I don't really
care about authenticated ones, just valid ones, and if you do that at
lmtp time, postfix has already received the email, and therefor it
would bounce if lmtp says it's not a valid recipient.

Ok, then we have different approaches.
So you are using *only* Postfix to check if a received user is valid, right?
I'm not even sure how you can use lmtp authentication to verify a delivery address, normally when postfix uses lmtp the email was accepted, and therefor would generate a bounce.
I can't find anything that wouldn't bounce using lmtp, in postfix or dovecot documentation.
If you follow this,
http://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP
it works OK. There is no bounce when Postfix submit mail to LMTP for delivery and the user is authenticated as valid.
