Trusted communication network
First Claim
1. A gateway, comprising:
- a processor; and
one or more non-transitory, machine-readable media coupled to the processor;
wherein the one or more non-transitory machine-readable media have stored instructions thereon, which, if executed by the gateway, cause the gateway to determine whether to send an outbound message from a member to at least one message recipient of the outbound message, said determination further comprisingapplying one or more filters to the outbound message, wherein the one or more filters include a spam filter;
modifying the outbound message to prevent a bounce attack;
extracting an attachment from the outbound message, when the attachment is filtered;
in response to detecting spam, quarantining the outbound message in an outbound quarantine without sending the outbound message to the at least one message recipient;
applying a disposition policy to the quarantined message; and
managing reputation feedback of the member based on the detected spam, wherein the member is penalized with a loss of access to a service, if the reputation feedback falls below a minimum value.

Abstract
A system includes a processing node configured to send authorized inbound messages to registered enterprise networks. An authorized message is a message that includes trusted source indicia. Trusted source indicia indicates that the message was sent by one or more of the processing node or an authenticated message transfer node associated with one of the registered enterprise networks. The system may further include an administration node configured to maintain registration of a plurality of message transfer nodes associated with the enterprise networks. A method includes receiving outbound messages from an authenticated message transfer node of an enterprise network, screening the messages for threats to determine whether to send the messages to associated recipients, applying a first message identifier to each message, wherein the first message identifier can be used to track the message and, for each message, sending the message to the associated recipient if no threats are detected in the message.

17. One or more non-transitory, computer-readable storage media having machine-executable instructions for determining whether to send an outbound message from a member to at least one message recipient of the outbound message, said instructions, when executed on a processor, configure the processor at least to:
-
apply one or more filters to the outbound message, wherein the one or more filters include a spam filter; modify the outbound message to prevent a bounce attack; extract an attachment from the outbound message, when the attachment is filtered; in response to detecting spam, quarantine the outbound message in an outbound quarantine without sending the outbound message to the at least one message recipient; apply a disposition policy to the quarantined message, wherein the disposition policy is a deliver only after approval policy; and manage reputation feedback of the member based on the detected spam, wherein the member is penalized with a loss of access to a service, if the reputation feedback falls below a minimum value. - View Dependent Claims (18, 19, 20, 21)
