One of the places to change this behaviour is within /etc/kolab/kolab.conf

I've attached mine below (which is quite the opposite of what you demand). Theres a default for kolab and a domain specific definition. Maybe you can adapt it to your needs.

        0: {
        "{0}@{1}": "format('%(surname)s', '%(domain)s')"
        },
        1: {
        "{0}.{1}@{2}": "format('%(givenname)s'[0:1].capitalize(), '%(surname)s', '%(domain)s')"
        },
        2: {
        "{0}@{1}": "format('%(uid)s', '%(domain)s')"
        },
        3: {
        "{0}@{1}": "format('%(givenname)s.%(surname)s', '%(domain)s')"
        }
        }
