摘要:
A message header of an email message can be identified. The message header can comprise of an exemption field which specifies one or more email addresses that is prohibited from receiving the email message. The sending email address can be associated with a sender node and the one or more email addresses is associated with a prohibited node. The sender node and the prohibited node can be arbitrarily linked within a network that is a social structure comprising of one or more individuals and organizations which can be connected by one or more specific type of interdependency. The network can be modeled as a graph which can be a mathematical structure modeling pairwise relations between nodes and edges. The email message can be conveyed to multiple email addresses except the one or more email address associated with the exemption field.
