[Dovecot] 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.

Yes.
