I just installed scalix on Ubuntu 6.10 with the help of the Manual Installation http://www.scalix.com/wiki/index.php?title=Manual_Installation guide.
The setup was fine but I wasn't able to send mails since there was an ldapmapper error. I change the default port but didn't change the ldpa config.
Perhaps someone could add http://www.scalix.com/wiki/index.php?title=Howto_-_Change_the_default_Scalix_ldap_port_from_389 or especially
/etc/sysconfig/ldapmapper
Finally, don't forget to change the ldapmapper. This is the complete file, as it only has one config line. Notice the ldapmapper(8) part - there's a man page, so go check it out too if you're interested!
#
# Scalix ldapmapper(8) options
#
LDAPMAPPER_OPTIONS="-L ldap://%s:3890"
because this was what I "forgot".
Besides of that: great howto
