Hello,
Following Jan-Frode's advise I am trying this configuration:
{postfix} ---lmtp---> {director} ---lmtp---> {dovecot}
so I have two dovecot instances for director/proxy and lmtp delivery on ports 1024 and 24 respectively.
whilst for imap connections I can specify a pool of imap backend servers via 'director_mail_servers' it seems is not possible with lmtp.

how I can redirect incoming lmtp request to backend lmtp servers (and not just one)? what I'm missing here?
