dovecot - Sep 2010 - LMTP proxying strategy with multiple recipient delivery

Hi Timo and All,
how does Dovecot act when an MTA tries to deliver a multiple recipient 
message to a LMTP proxied system?

Does it uses server affinity table for each recipient?
I use lmtp_destination_recipient_limit = 1 setting in postfix to avoid 
multiple recipient delivery. Is it right?

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

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

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

Probably.
