my question is what is benefit implementing LMTP service replacing LDA i have dovecot 2.1.8 with vpoipmail+qmail and about 500 users now i'm using LDA and i'm interested on LMTP service.

with LMTP...

• you dont need to care about mail filesystem permissions
• you can use dovecot lmtp proxy and/or director
• you don't need to spawn a new process for each message

One of the (potential) benefit is that a LMTP, because it can handle multiple recipients, has the ability to optimize I/O (or storage?) by using hardlinking to a single copy of a message (deduping). I don't know if Dovecot takes advantage of this in any way though.
