Yes, I think it will be right to remove the extra web mail and the link if it is not needed. The essensial thing, is as I see it, that everything that is there, is working proporly and ok, so there is no dead links or other "visible errors". (Neither hidden errors either of cource.)
I think that the asteriskinfo section can be removed as all the info in that section (I believe) is available via a separate shell logon, and the standard Astersik commands.
