Thanks for the pointers Axel. Let me describe first my environment and 
how I'm intending to slot Kolab in.

We're using a number of Plesk servers which are storing the mailboxes 
for our hosted domains. In front of them we're using a mail proxy 
cluster based on Postfix and Dovecot. Dovecot acts as proxy and has been 
configured as per 
https://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy article. 
Postfix is configured to use rimap saslauthd auth mechanism for SMTP 
authentication.
Now, what we're looking at is adding calendar / contacts / tasks / notes 
groupware abilities and Kolab's version of Roundcube seems to offer a 
seamless integration. One of the options we have is to import the 
existing domains & users into Kolab's LDAP *without* setting up 
mailboxes in Kolab, since all the mailboxes are in Plesk. Kolab 
authenticates the user against LDAP, but Roundcube will connect for IMAP 
to the Dovecot proxy instead of using the existing Cyrus IMAP service.

Looks like the multi-domain approach might work in my case.
