dovecot - Feb 2015 - how to run dovecot imap on separate server from postfix?

Hello Reindl,   thank you for the response.

I want to make sure that the postfix delivery does  not give up trying to
get the email delivered when the  lmtp host is not reachable.      I do not
just want to assume that the default settings are correct for us.

 Are there  postfix or other settings which can be checked and adjusted?

postfix was *not* written by a moron and hence in any case any mail in 
the queue will be re-tried until "maximal_queue_lifetime" is reached

there is no difference if lmtp is a unix socket or on the network 
because nobody can say for sure that the lmtpd on localhost is reachable 
365/7/24 and hence any sane MTA handles errors properly
