Two SWA questions --- Ports and How to Remove?

[BigBirdy]

1: With a SWA server on a DMZ running only tomcat and the Scalix SWA component, connecting to an internal Scalix mail server, which ports are required to be open between the DMZ and internal network, Scalix server, in order to connect. Is it only the LDAP port 389?

2: Also, once we have a seperate SWA server configured and working properly, what is required to disable/remove the SWA from the original server? Would this simply be to shutdown tomcat? or is there also other Scalix services related to SWA that could be shut down/removed to conserve memory and resources?

[ls-al]

SWA needs the following services:
- IMAP (143)
- LDAP (389)
- SMTP (25)

If you also dont want to use SAC on your Scalix server you can shut down and disable tomcat.
To remove just SWA you have to:
-remove scalix-swa rpm
-remove the $TOMCATDIR/webapps/webmail directory
-remove $TOMCATDIR/conf/Catalina/localhost/scalix-swa.xml file
-remove $TOMCATDIR/work/Catalina/localhost/webmail directory
-restart tomcat of course
(hope I catched all)
