OK, I have Scalix 11.2 installed on Suse OSS Linux 10.3
To change the default port from 80 to 8080 i had to edit the following files
(please note this changes the web admin port to 8080 as well, i have not tested mobile browsing with this configuration):
1. /var/opt/scalix/<instance>/tomcat/conf/server.xml
and changed
<Connector port="80" maxHttpHeaderSize="8192"
to
<Connector port="8080" maxHttpHeaderSize="8192"
2. /etc/opt/scalix-tomcat/connector/ajp/instance-scalix.conf
and changed
<VirtualHost <hostnamehere>:80>
to
<VirtualHost <hostnamehere>:8080>
Did the exact same thing to /etc/opt/scalix-tomcat/connector/jk/instance-scalix.conf
3. /etc/opt/scalix-tomcat/conf/server.xml.in
and changed
<Connector port="80" maxHttpHeaderSize="8192"
to
<Connector port="8080" maxHttpHeaderSize="8192"
4. /etc/opt/scalix-tomcat/ports
and added
<hostname>+8080 directly below: <hostname>+8005
This worked for me, let me know if it's successful for other distributions of linux
