According to what I've read on mailinglists and the postfix doc, its
sufficient to change the smtpd settings in master.cf to disable the
chroot of postfix... 

saslfinger -s gives me:

-- content of /etc/postfix/sasl/smtpd.conf --
pwcheck_method: authdaemond
log_level: 7
mech_list: PLAIN LOGIN
authdaemond_path: /var/run/courier/authdaemon/socket


-- active services in /etc/postfix/master.cf --
