The python code you are looking at is used for Wallace (the content 
filter), the Kolab daemon (that synchronizes changes in LDAP to 
mailboxes), the command-line interface ("kolab lm", "kolab cm", "kolab 
set-mailbox-metadata").

The Kolab web admin doesn't in fact do anything with IMAP.

A configuration setting in /etc/kolab/kolab.conf is supposed to control 
which IMAP backend-specific routines the Kolab daemon and CLI will 
attempt to use. This setting is "imap_backend" in the [kolab] section.

I've only very briefly looked at running a Kolab daemon against 
Dovecot, but it doesn't seem Dovecot's administration is done over IMAP 
(i.e. I did not seem to be able to login as an administrator user in 
order to create/rename/delete mailboxes for users).

Long story short it seems that for Dovecot, we definitely need the IMAP 
backend-specific routines (that do something entirely different than the 
Cyrus IMAP backend does), where "create a new mailbox for a new user" is 
redirected to whichever routine Dovecot is used to having executed.

In fact, the two Kolab components that hook in to postfix (other then 
the settings we set up Kolab with, that are LDAP lookup tables for 
recipient addresses and such and so forth), are Wallace (the content 
filter, not really hooking in) and the Kolab SMTP Access Policy (that 
enables authorization of use of sender and recipient email addresses, 
such as in use in a delegation scenario).
