how to run dovecot imap on separate server from postfix?

Hello

we are using version 2.2.13 on debian.

currently imap runs on the same system as postfix , spamassassin and other mail related software.

I'd like to move dovecot imapd and mail storage to its own system.

I've search google and wiki and could not see how to do so.

could someone please point me in the direction to that done? I like reading documentation..

here is more info on our set up:

postfix: # grep dovecot /etc/postfix/* /etc/postfix/main.cf:mailbox_transport = lmtp:unix:private/dovecot-lmtp /etc/postfix/main.cf:smtpd_sasl_type = dovecot

kind regards Rob Fantini
