PureMessage Download Server
If installing PureMessage from a download server, you must allow HTTP access for downloads over port 80 to the host where the PureMessage installation is being performed.
If you use a proxy server to access the internet, ensure that you have set the
HTTP_proxy environment variable.
HTTP_proxy should be set to a
value of the form
http://username:firstname.lastname@example.org:PORT for proxy servers that
require a username and password.
