how does Dovecot act when an MTA tries to deliver a multiple recipient message to a LMTP proxied system?

It also tries to forward the same message with one DATA and multiple RCPT TOs.

I use lmtp_destination_recipient_limit = 1 setting in postfix to avoid multiple recipient delivery. Is it right?

Shouldn't be necessary. It's been tested to work with multiple recipients, but bugs are of course still possible.

I use lmtp_destination_concurrency_limit = 1 too, but i think that it's useless or, maybe, it can make performance worst.

Probably.
