Does Postini require extensive integration with existing systems?
No. Postini provides its services as a managed service, requiring minimal integration. For BayArea.net customers we simply update your DNS records so that the MX records point to Postini for pre-processing before mail is delivered to the destination server. For BayArea.net customers that run their own SMTP server a simple DNS MX record update will be required to enable the Postini services. Mail delivery follows a conventional format that also lends itself to the automatic fail-over that is typical for any MX record.
