Abstract: A system are blocks and filters e-mails at the enterprise level. Incoming e-mails having an incoming domain are received at an e-mail server. Incoming domains are compared to a list of blocked domains. in response to identifying the incoming domain within the list of blocked domains, the incoming e-mail is blocked from delivery to an intended recipient. Incoming domains are then compared to a first predefined category. If the incoming domain is identified within the first predefined category, the intended recipient is compared to the first distribution list. If the intended recipient is identified within the first distribution list, then the incoming e-mail is delivered to the intended recipient.

Abstract: The present invention generally relates to computer systems and methods of integrating a central system and a satellite system for automatically updating software and providing diagnostics for a product system to be shipped to an end customer.
