[cobalt-users] upgrade RAQ2 to RAQ4 or XTR?

["Linuxman" <linuxman@xxxxxxxxxxxxxxxx>]

I need to upgrade my RAQ2, and I have a few desires, what's best? The sales
folks told me that both the RAQ4 and XTR will do what I need and even water
the plants and walk the dog, so I come to you for the truth.

1) I need a better mailing list manager so people can subscribe and
unsubscibe themselves from lists. I cant do that on the RAQ2. Will the RAQ4
do this, or do I need to do to the XTR? Is there a simple add on that even a
dummie like me can put on the RAQ4?

2) I need working digests for mailing lists. RAQ2 or XTR? Can this perhapps
be added easily to teh RAQ4 if it's not native?

3) I would like to, but not required, be able to set administrator right to
parts of a domain. RAQ2 or XTR?

4) My RAQ2 gives me CPU overload messages once a week at 23 domains. What
can I expect from a RAQ4 or XTR?

Thanks,
Fred
